Beyond the Score: Using AI to Translate CVEs into Real-World Business Risk

By: Rapid7
15 June 2026 at 10:44

Security leaders rarely struggle to gather data, but they often struggle to turn that data into something clear and meaningful for the business. In a typical week, a CISO might receive a report listing hundreds or even thousands of vulnerabilities, most of them accompanied by CVSS scores that make the entire list look urgent, while also managing the wider set of operational, regulatory, and strategic demands that already come with the role.

That difficulty becomes more obvious when the same information has to be carried into the boardroom, where the questions are rarely about CVE IDs or exploit counts in isolation. What leadership wants to understand is whether the organization’s revenue, uptime, legal exposure, or broader resilience could be affected, and how quickly those risks need to be addressed.

This is where many security programs lose momentum, because the technical view of severity does not always line up neatly with the business view of consequence. Bridging that gap has traditionally been slow, manual work, which is one reason AI is starting to matter more in vulnerability management: it can help translate technical findings into business context that is clearer, faster to act on, and easier for leadership to understand.

Why CVSS alone does not reflect real-world business risk

For years, the industry has relied on CVSS as a quick way to judge urgency, and while the framework does account for factors such as attack vector, attack complexity, and other attack requirements, the score is still calculated in isolation and often misses the conditions that shape real risk inside an organization. A CVSS 9.8 vulnerability affecting a legacy printer in a segmented branch office may look critical on paper, but it is unlikely to carry the same business impact as a 7.5 vulnerability affecting an internet-facing database that holds sensitive customer data.

One of the long-standing weaknesses of static scoring is that it tells you how severe a flaw may be in theory, but not how much disruption it could cause in your own environment, how exposed the affected asset is, or how closely it is tied to a revenue-generating or business-critical process. That is where AI becomes more useful, because it can add the missing context that helps security teams judge not just how serious a vulnerability looks, but how much it matters in practice.

Machine learning models can now process a much broader set of inputs, including attacker activity, exploit availability, internal network topology, and the business value attached to the asset or process involved. Rather than leaving teams with a static queue of scores, that creates a live view of risk shaped by reachability, exposure, and business consequence, making it easier to separate technical severity from actual organizational risk.

How AI helps connect vulnerabilities to business impact

One of the more practical ways AI can improve vulnerability management is by helping security teams connect technical findings to the parts of the business they actually affect. A vulnerability tied to an obscure IP address may not mean much on its own, but the picture changes quickly when that asset is identified as part of a regional payment system, a customer-facing portal, or a supply chain application the business depends on. That kind of asset attribution has traditionally taken time, context, and manual investigation. AI can help shorten that process by linking technical findings to business function much more quickly.

Instead of relying only on severity scores or yesterday’s alerts, AI can weigh a broader set of signals, including exploit activity, attacker behavior, asset exposure, and internal topology, which gives security teams a more grounded way to judge where risk is most likely to become operationally significant. The benefit is not simply speed, but a clearer picture of which vulnerabilities are most likely to affect revenue, uptime, or business continuity if they are left unresolved.

At the leadership level, this same approach can help turn a large volume of technical output into something more usable. Rather than forcing CISOs to manually translate thousands of low-level alerts into board-facing language, AI can support that reporting by summarizing likely business impact, highlighting where exposure is growing, and making it easier to explain how remediation work is reducing financial and operational risk.

Two vulnerabilities, two very different business outcomes

To see how this plays out in practice, it helps to compare two vulnerabilities that might appear similarly urgent in a standard scanner, but look very different once business context is added.

Vulnerability A: The ghost in the machine

A scanner flags a CVSS 9.8 critical remote code execution flaw in an aging media server. On paper, that score suggests immediate attention. Once more context is added, the picture changes. The asset sits on a segmented guest Wi-Fi VLAN, has no path to the corporate core, and has not been linked to in-the-wild exploitation for more than two years. In practical terms, the business impact is low. The issue still needs to be addressed, but it is unlikely to justify urgent remediation ahead of higher-consequence exposures.

Vulnerability B: The quiet threat

  • A second finding carries a lower CVSS 7.2 high severity score, but affects a common web framework running on the organization’s primary customer portal. When AI correlates that vulnerability with asset and business context, the risk profile changes quickly. The portal is identified as a critical business process, estimated to support $250,000 in transactions per hour, while external signals point to growing exploit interest around the same framework. In that case, the business impact is far more serious. What looks like a lower-priority technical issue becomes a potential source of revenue disruption measured in millions per day.

This is where AI-assisted prioritization becomes useful. It helps teams move beyond the assumption that the highest score always deserves the fastest response and instead focus on the vulnerabilities most likely to create operational or financial harm. In practice, that means spending less time working through a queue in score order and more time reducing the exposures that matter most to the business. 

How AI helps CISOs explain vulnerability risk in business terms

When security leaders can move beyond reporting how many patches were deployed and begin showing how exposure is changing in financial or operational terms, the conversation becomes much more useful. A reduction in mean time to remediate may matter to a security team, but it carries more weight at the leadership level when it is tied to a lower likelihood of downtime, reduced regulatory exposure, or less risk to a revenue-generating service.

When vulnerability data is tied to business context, it becomes easier to justify automation, tooling, or headcount based on their contribution to resilience, continuity, and measurable risk reduction, rather than on activity alone. At that level, the conversation is less about severity scores and more about what is exposed, what it could affect, and where action matters most.

One of the more practical benefits of AI is that it can help security teams explain risk in a way leadership can act on. Instead of adding another layer of technical output, it can support clearer reporting on why one issue matters more than another, what is most likely to affect the business, and where action should come first.

As attack surfaces expand and exploit timelines continue to shrink, the gap between technical findings and business understanding will only become harder to manage. Organizations that can connect those two views more effectively will be in a much stronger position to prioritize the right work, explain risk more clearly, and make vulnerability management a more meaningful part of business decision-making.

CISA directive orders agencies to prioritize vulnerability patching in a new way

10 June 2026 at 12:07

The Cybersecurity and Infrastructure Security Agency on Wednesday ordered federal agencies to prioritize vulnerabilities based on four criteria, as part of push to “patch smarter, not harder.”

Federal agencies should emphasize patches for vulnerabilities that affect a publicly exposed asset, allow an attacker to fully automate exploitation, give attackers the ability to take over control of a system or relate to evidence of active, real-world exploitation, CISA declared.

CISA acting director Nick Andersen previewed the binding operational directive (BOD) Tuesday, framing it as a rethinking of vulnerability management more broadly.

“This Directive provides clear definitions, timelines and criteria that enhances transparency, predictability and agencies’ resource planning to execute more effective vulnerability remediation,” Andersen said in a statement. “CISA is leading and collaborating with federal civilian agencies to stay ahead of our adversaries as tactics, technologies and vulnerabilities change.”

BOD 26-04 sets forth timelines for how quickly agencies must fix a vulnerability based on how many of the four criteria it meets. If it meets all four, for example, agencies need to fix it within three days and carry out a “forensic triage” to assess whether their systems were compromised. 

More generally, agencies must immediately update their vulnerability management policies, including establishing a process for ongoing remediation of known, exploited vulnerabilities (KEVs) on CISA’s “must-patch” list. Within 60 days, agencies need to update their processes for remediating common vulnerabilities, and within 180 days, agencies must meet the order’s remediation timelines.

The directive is motivated in part by how artificial intelligence is shifting the window from vulnerability discovery to weaponization, and CISA said it reflects priorities in an executive order on AI that President Donald Trump signed last week.

BODs aren’t mandatory for anyone outside of federal agencies, but CISA encourages the private sector to embrace them. CISA officials said in a blog post about the need to “patch smarter, not harder” that “defenders are already struggling to keep up.”

“Artificial intelligence is assisting both researchers and adversaries in identifying flaws in software, vastly increasing the pace at which new vulnerabilities are discovered,” wrote Chris Butera, acting executive assistant director for cybersecurity, and Jonathan Spring , senior technical adviser. “Per Verizon’s 2026 Data Breach Investigations Report, only 26% of vulnerabilities on CISA’s Known Exploited Vulnerabilities (KEV) Catalog were fully remediated by organizations in 2025, a drop from the previous year’s 38%. The median time for full resolution rose to 43 days.”

The move from weeks to days for agencies to patch the most urgent vulnerabilities is something CISA has discussed with some agencies to see if it’s doable, Butera told reporters Wednesday. At one large agency CISA analyzed, just 1% of vulnerabilities fell into the 3-day window, while 60% could be deferred to the next system upgrade.

“We’ve engaged with a few federal agencies ahead of this directive and tried to socialize some of these new time frames,” he said. “We really believe we should be able to free up some time to patch the most urgent vulnerabilities faster, while allowing for more regular patch cycles for some of the lower risk vulnerabilities.”

Patrick Garrity, a security researcher at VulnCheck, said the CISA directive joins similar guidance out of India and the United Kingdom.

“It’s clear the momentum is growing and pushing in the right direction,” he told CyberScoop. “The new directive aligns exactly with the approach we’ve been taking with customers for years, leveraging exploit intelligence to focus on the subset of vulnerabilities that enterprises, governments and vendors really need to address. While it’s mandated for federal organizations, it’s something the private sector should pay attention to as well.”

Tod Beardsley, vice president of security research at runZero and former KEV section chief at CISA, wrote on LinkedIn that there are several noteworthy potential impacts of the BOD, among them that he thinks three-day deadlines will end up being frequent.

“I remain dubious that a three day deadline spread across more than a hundred agencies is an achievable patch cadence today, but we’ll all find out together,” he said.

Patch Tuesday - June 2026

9 June 2026 at 17:04

Microsoft is publishing 200 vulnerabilities on June 2026 Patch Tuesday. Microsoft is not aware of exploitation in the wild for any of these vulnerabilities, and is aware of public disclosure for three. This is similar to last month’s Patch Tuesday, however several of last month’s vulnerabilities ended up on CISA KEV in the days following their publication. So far this month, Microsoft has provided patches to address 360 browser vulnerabilities, which is an order of magnitude more than has been typical in any given month over the past few years. As usual, browser vulns are not included in the Patch Tuesday count above. Indeed, the vast, and presumably sustained, uptick in the number of browser vulnerabilities has led to Microsoft no longer enumerating Chromium CVEs in the Security Update Guide. Other vulnerability categories, especially Linux kernel vulnerabilities, are seeing a similar increase in AI-assisted vulnerability reports.

What's the opposite of coordinated disclosure?

In recent weeks, an independent vulnerability researcher going by the pseudonym Nightmare Eclipse has attracted significant attention by publishing details of six Microsoft vulnerabilities, including elevation of privilege vulnerabilities in Defender, and a Secure Boot disk encryption bypass. The researcher provided full proof-of-concept code for some, and provided  significant-but-incomplete detail around the path to exploitation for others. Microsoft has confirmed that these disclosures were not coordinated, and it is clear that the relationship between this researcher and Microsoft is less than cordial. Two of the disclosures emerged in the hours after last month’s Patch Tuesday, which provides maximum visibility, while limiting Microsoft’s ability to respond without out-of-cycle patches.

At time of writing, Microsoft has provided mitigation advice and patches for CVE-2026-33825, CVE-2026-45585, CVE-2026-45498, and CVE-2026-41091, leaving only two elevation of privilege vulnerabilities unpatched, known as MiniPlasma and GreenPlasma. However, a recent blog post by Nightmare Eclipse with the title “7” has been widely interpreted to mean that there is at least one more vulnerability to come. The post contained no content other than an image of Albert Vesker, a character from the Resident Evil video game series who formerly worked as a researcher for a technology corporation before going rogue. Any inference around the possible meaning of the image is left as an exercise for the reader.

Given the timing of last month’s disclosures in the hours following Patch Tuesday, a further high-friction disclosure today would perhaps be unsurprising. Indeed, a new blog post and a new GitHub account from the same researcher have emerged in the hours following Microsoft’s publication of the June 2026 Patch Tuesday updates. The apparent seventh disclosure is nicknamed RoguePlanet, and appears to describe another elevation of privilege to SYSTEM in Defender.

It is not at all difficult to understand why Microsoft and many blue team practitioners are deeply alarmed by the partial or even full disclosure of proof-of-concept code for an ongoing series of vulnerabilities affecting fully-patched Windows systems. However, multiple leading voices in the broader vulnerability disclosure community have expressed concern that Microsoft’s invocation of the Digital Crimes Unit in a May 27, 2026 blog post may yet prove counterproductive, especially if it causes other researchers to back away from mutually beneficial engagements with MSRC. A few days later, MSRC issued a further statement clarifying that they have no intention of pursuing action against security researchers, but only those who break the law or engage in malicious activity causing real harm. For now, one safe conclusion is that this unusually sensational Microsoft vulnerability management story arc is far from over.

HTTP/2: denial of service

Every so often, a new round of denial of service vulnerabilities emerge which affect web servers implementing HTTP/2 and HTTP/3 standards. This class of vulnerabilities is likely to expand further as researchers, including the discoverers of CVE-2026-49160, use advances in LLM capability to probe not just specific software, but also the standards on which software rests. Microsoft warns that exploitation leads to uncontrolled resource consumption over a network, and expects that exploitation is more likely. The advisory credits both a third-party research firm and OpenAI’s Codex.

Microsoft has not yet directly addressed another HTTP/2 vulnerability which allows trivial denial-of-service against the default HTTP/2 configuration of multiple web server platforms, including Microsoft IIS. CVE-2026-49975, also known as HTTP/2 Bomb, became public knowledge a week ago. This denial of service works by exhausting memory on the target server, and unlike a distributed denial of service attack, there is no requirement that an attacker control a large amount of bandwidth. Patches are available for NGINX and Apache, with IIS presumably to follow at some point. If practically possible, disabling HTTP/2 is a valid mitigation.

PowerToys: SYSTEM EoP

The Microsoft PowerToys utility provides a wide variety of useful control and configuration options for Windows power users which aren’t otherwise easily accessible. It turns out that PowerToys also offers an undocumented extra: local elevation of privilege to SYSTEM via successful exploitation of CVE-2026-42902. It is worth noting that the fix was included in PowerToys v0.99.1 on April 29, 2026, without any apparent mention in the release notes. Attackers with patch-diffing toolkits may well take note of this discrepancy.

Microsoft lifecycle update

There are no significant Microsoft product lifecycle changes this month. SQL Server 2016 moves beyond regular extended support and into the pay-to-play Extended Security Updates (ESU) phase after July 14, 2026. On that same date, SharePoint 2016 and 2019 will also move past extended support, but since there’s no ESU available, the only remaining option for fully-supported self-hosted SharePoint after the middle of next month will be SharePoint Subscription Edition.

CISA is rethinking how it prioritizes risks and vulnerabilities for feds, private sector

9 June 2026 at 12:27

The Cybersecurity and Infrastructure Agency wants to fundamentally reevaluate how it prioritizes risks and vulnerabilities, both for privately-owned critical infrastructure and within the federal government, acting director Nick Andersen said Tuesday.

The plans include a binding operational directive for federal agencies set to be published Wednesday and getting more specific with critical infrastructure owners and operators about which assets they need to protect most and how, Andersen said while speaking at an event hosted by Axonius in Washington, D.C. and talking with reporters afterwards.

The binding operational directive looks to revise how federal agencies do vulnerability management, he said. “Overall, our approach to date has been ‘A patch is released, apply this patch as quickly as you can,’” he said.

“We’re really asking people to take more of a focus on risk associated with each vulnerability. Is it with an asset that is internet-exposed? Does it align to a KEV entry?” he said, referring to CISA’s list of known exploited vulnerabilities. “Is it automatable in its exploitation? Really, we need to be able to highlight that some patches just aren’t as important as others, and plugging the holes for some vulnerabilities is simply not as important as others.”

Andersen said he has made setting the right priorities the focus of his tenure.

“We have to be okay with saying there are some systems that are less important than others, there are some elements of critical infrastructure that are less important than others,” he said. “Those things are very easy for us to rationalize [for] physical crises, but we need to start wrapping our minds around how we’re going to do that during cyber crises.”

Andersen said artificial intelligence-enhanced threats have fueled the directive in part, based on “a recognition that we’re a different dynamic environment with the shorter timeline to weaponization and exploitation,” but the discussions on the directive have been going on for months, before the splashy announcements about frontier AI models and the risks they might deepen. Wednesday’s directive is unrelated to the AI-focused executive order released by the Trump administration last week.

The idea of prioritizing certain potential hacking targets over others isn’t a new one in critical infrastructure, with concepts like “Section 9” designations under a 2013 executive order for entities whom an attack upon could have catastrophic effects; “systemically important critical infrastructure” designations, as recommended by the Cyberspace Solarium Commission; or the creation of the National Risk Management Center established during President Donald Trump’s first term but now the subject of proposed budget cuts.

Andersen said past concepts haven’t worked well, citing Section 9 designations as an example.

“We would sit here and say, ‘Congratulations, you’re with this company, and you’re a Section 9 entity, isn’t that fantastic?’” he said. “That’s really not the level of fidelity that we have to be able to get to to have a real measurable conversation about risk. I need to be able to go to a company and say, ‘Here’s the specific function you’re supporting that makes you more critical. Let’s have a conversation about the specific assets that support that function, and how do we get to a measurable level of resilience for those assets?’”

Those discussions need to get down to a “fine grain,” Andersen said.

“If I’ve got a major bank that I’m talking to, is it as important to me that the bank’s process that supports the bulk payment system is resilient, or is it just as important to me that the branch location two blocks away is continuing to operate?” he said. “Those things just are apples and oranges, even though it’s the same entity that might be affected.”

CISA’s capabilities under the Trump administration have drawn considerable scrutiny, given deep budget cuts at the agency, with more planned. The administration is now making moves to hire back personnel.

Andersen said the agency is working to hire 329 people, and will have job offers out to 182 of them by the end of June. He said the emphasis of the first tranche of hires under the hiring sprint is operational capabilities, meaning areas like emergency communications, infrastructure security and regional personnel.

The agency also has had some of its work hampered by the government shutdowns, such as the delay in plans for town-hall meetings about implementation of the Cyber Incident Reporting for Critical Infrastructure Act of 2022, which will require key owners and operators to report major incidents within 72 hours.

Andersen said he couldn’t set a date for finalization of regulations related to the law — which had already been delayed prior to any funding lapses — with those town halls now scheduled to begin next week.

“We could have a lot of comments that come to us and really radically change our way of thinking about what the need is here,” he said. “But our focus is just on what’s the original congressional intent behind CIRCIA. what is the greatest need that we’re going to be able to serve, and how it’s going to be able to further the mission that we have for the nation.”

Attackers are exploiting Palo Alto Networks defect that initially flew under the radar

1 June 2026 at 18:29

Researchers and threat hunters are scrambling to respond to an actively exploited authentication-bypass vulnerability affecting Palo Alto Networks customers’ firewalls. 

The company initially tagged CVE-2026-0257 with a medium-severity rating when it disclosed the defect May 13, but quickly reassessed it as critical after Rapid7 observed and confirmed active exploitation in the wild. The Cybersecurity and Infrastructure Security Agency followed suit, and added the vulnerability to its known exploited vulnerabilities catalog Friday.

The escalated threat posed by the defect, which allows remote attackers to bypass security restrictions and establish a VPN connection to an affected firewall, showcases how quickly a seemingly mild vulnerability can turn into an urgent warning. 

“Palo Alto Networks is actively monitoring limited exploitation attempts targeting CVE-2026-0257 on unpatched PAN-OS devices where mitigations have not been applied,” a company spokesperson said in a statement. The company on Friday urged all customers to immediately apply the patch or follow its recommended steps for mitigation. 

The vendor and Rapid7, which first observed exploitation May 17 in a customer environment, declined to say how many organizations are impacted thus far. Yet, Douglas McKee, director of vulnerability intelligence at Rapid7, warned: “We’ve continued to see new victims roll in, including a couple of customers hit within just an hour of each other during a second wave of activity” on May 21. 

Jake Knott, security researcher at watchTowr, told CyberScoop the vulnerability and resulting exploits follows a recurring trend wherein attackers target exposed network edge devices and rapidly identify, develop and weaponize exploits for initial access. 

“This is yet another authentication bypass on a device whose sole job is to guard the front door to an organization’s network,” he said. “What stands out is how simple it is — an attacker can forge a valid authentication cookie using nothing more than the appliance’s publicly available TLS certificate. The entire exploit is a single HTTP request.”

The vulnerability has a few requisites that limit exposure, specifically posing risk to some Palo Alto Networks customers running GlobalProtect portal or gateway configured to enable authentication override cookies. 

“The cookie encryption and decryption certificate must be reused with another feature, which potentially exposes the public key for that certificate,” said Caitlin Condon, vice president of security research at VulnCheck.

“It’s difficult to say how many deployments meet those criteria for exploitability, but Palo Alto Networks firewalls have a very large footprint, which means even uncommon configurations can present significant attack surface area,” she added.

Rapid7 said the same attacker or group is likely responsible for both waves of exploitation last month, but in many cases attackers are not establishing a full VPN connection or moving to other parts of the impacted network. 

The attackers are “highly opportunistic and clearly monitor the security research community,” McKee said. “Attackers are purposefully weaponizing medium-severity vulnerabilities, which are typically lower priority or blind spots for organizations.”

Multiple threat clusters are swarming to the opportunity and quickly adapting to published research.  Researchers have not attributed the malicious activity to any specific threat groups. 

“Their exact origins and long-term objectives remain unclear, as they currently seem focused purely on opportunistic initial access rather than targeted, long-term espionage,” McKee said. 

Palo Alto Networks said it discovered the vulnerability internally through its use of frontier AI tools. Yet, within days of its public disclosure, initial assessments were proven inadequate.

“This is a pattern we continue to see — the urgency only arrives after exploitation is underway,” Knott said. “Organizations that wait for confirmation of active exploitation before patching will consistently find themselves reacting too late.”

Attackers hit vulnerabilities hard last year, making exploits the top entry point for breaches

19 May 2026 at 17:19

Attackers couldn’t get enough of the vulnerabilities at their disposal last year, making exploits the top initial access vector across more than 22,000 breaches Verizon analyzed in its latest Data Breach Investigations Report released Tuesday.

The massive annual study uncovered a surge of exploited vulnerabilities during a one-year period ending in October 2025. Exploited defects accounted for 31% of all known initial access vectors, jumping from 20% the previous year. 

The uptick in exploited vulnerabilities is a reflection of the “sisyphean cause” of vulnerability management, researchers wrote in the report. “Put quite simply, there are often too many vulnerabilities and not enough time for patching all of them.”

Organizations are struggling to keep up with the torrent of vulnerabilities affecting technology across their systems. This slide is especially worrisome, and declining, among defects in the Cybersecurity and Infrastructure Security Agency’s known exploited vulnerabilities catalog.

Only 26% of the critical vulnerabilities in CISA’s catalog were fully remediated by more than 13,000 organizations Verizon studied in 2025, marking a drop from 38% the year prior. 

“There is also a worse result for the median time elapsed for a vulnerability to be fully patched by detection,” researchers wrote in the report. “Our new median time is 43 days, almost two weeks longer than last year’s 32 days.”

Verizon also noted that the median number of KEV vulnerabilities that organizations had to patch jumped from 11 in 2024 to 16 in 2025.

CISA’s KEV catalog contained more than 1,500 CVEs as of February, and 65% of those were exploited during the previous year, according to the report.

Verizon identified the five most common weaknesses of CISA KEV CVEs in its report as out-of-bounds read, heap-based buffer overflow, use after free, external control of file name or path and access of resource using incompatible type.

Attacker motivations remained relatively consistent last year, with financially-motivated cybercriminals accounting for 88% of all breaches. Espionage-driven attacks from state-affiliated groups made up the remainder.

“Ransomware continues to be among the most disruptive and impactful types of breaches we see. Not unlike the price of everything from fast food to adult beverages in ballparks, it continues to trend upward,” researchers wrote in the report.

Ransomware accounted for 48% of all breaches last year, up from 44% in 2024. Yet, Verizon observed some positive trends in ransomware as well.

Ransom payments continued to decline, with 69% of victims reporting they didn’t pay, and the median payment slid from $150,000 in 2024 to almost $140,000 last year.

Tracking ransomware remains a challenge for researchers and authorities. 

“There is a growing disconnect between what is being reported and the reality of what has occurred, in no small part due to threat actors reusing old breaches, reposting breaches from other criminal partners and making up breaches out of whole cloth to help increase their notoriety in the criminal world,” Verizon wrote in the report. “We’re beginning to think that these cybercriminals might not be entirely trustworthy.”

Yet, despite the lack of indisputable data on ransomware activity, researchers concluded: “Ransomware is still the yoga pants of cybersecurity — ubiquitous, stubbornly popular and appearing in unexpected places near you.”

Cisco zero-day under ongoing attack by persistent threat group

15 May 2026 at 10:11

Attackers returned once again to a common target with a massive user base by exploiting a max-severity zero-day vulnerability affecting Cisco Catalyst SD-WAN Controller and Manager.

The threat group behind the “limited” number of attacks Cisco is aware of thus far are also linked to a series of previously disclosed vulnerabilities in the vendor’s firewalls and SD-WAN systems, the company said in a threat advisory Thursday.

The authentication bypass vulnerability — CVE-2026-20182 — has a CVSS rating of 10 and “behaves like a master key,” Douglas McKee, director of vulnerability intelligence at Rapid7, wrote in a blog post. 

“An attacker can present themselves to the controller as a trusted network router and, if the system accepts that claim without properly validating it, they can obtain the highest level of administrative access,” he added. “That is the cybersecurity version of a Jedi mind trick.”

Rapid7 discovered and reported the vulnerability to Cisco on March 9, and Cisco said it became aware of limited exploitation of the vulnerability earlier this month. The vendor disclosed and released a patch for the vulnerability Thursday, and the Cybersecurity and Infrastructure Security Agency quickly added the defect to its known exploited vulnerabilities catalog.

Cisco did not explain what occurred during that two-month window. Yet, the disclosure and warning from researchers marks another challenge for Cisco customers that have confronted a flood of actively exploited vulnerabilities affecting the vendor’s network edge software since late February. 

Cisco isn’t the only security vendor facing an onslaught of attacks on its customers, but it is among the most heavily targeted. CISA has added seven vulnerabilities affecting Cisco SD-WANs and firewalls to its known exploited vulnerabilities catalog in less than three months.

Cisco Talos researchers attributed the latest round of zero-day attacks to UAT-8616, the same attackers that exploited a pair of separate zero-days in Cisco’s network edge software for at least three years before the activity was discovered and reported in February. 

The company, which described the exploitation of the new zero-day as ongoing, once again declined to answer questions about the origins or motivations of UAT-8616. 

“We strongly recommend customers apply the available fixed software releases and follow the guidance provided in the advisories and Cisco Talos blog,” a spokesperson for the company said in a statement.

Cisco Talos researchers also warned that UAT-8616 and at least 10 other threat groups have chained together and achieved “widespread in-the-wild active exploitation of three vulnerabilities in unpatched Cisco Catalyst SD-WAN Infrastructure.” The company previously disclosed and released patches for the vulnerabilities — including CVE-2026-20122, CVE-2026-20128 and CVE-2026-20133 — in February. 

Rapid7 said it discovered the latest critical authentication bypass vulnerability when it was researching CVE-2026-20127, a previous zero-day the Five Eyes identified and confirmed as actively exploited by UAT-8616 in late 2025. Authorities and Cisco waited at least two months to disclose and patch the vulnerability, and share emergency mitigation guidance.

That campaign, which got underway at least three years prior, marked the second series of actively exploited zero-days in Cisco edge technology in less than a year. Both campaigns prompted CISA to issue emergency directives months after the attacks were first detected, and both attack sprees were underway for at least a year before they were discovered. 

The latest zero-day, which bypasses authentication in the same control-plane service as CVE-2026-20127,  requires no credentials or prior knowledge of the target environment for exploitation, Jonah Burgess, senior security researcher at Rapid7, told CyberScoop.

“Cisco confirmed it affects all deployment types, including on-premises, cloud, and FedRAMP environments. The SD-WAN Controller manages routing and policy for the entire overlay network, so a single compromised controller can potentially give an attacker influence over every branch, data center, and cloud edge connected to that fabric,” Burgess added.

His colleague at Rapid7, McKee, said attackers have become very good at turning weaknesses in central network infrastructure into high-impact operations. 

“Compromising one branch router is useful. Compromising the controller that manages the entire estate is a very different conversation. Now you are talking about the ability to reroute traffic, intercept communications, push malicious configuration, or simply break connectivity across the whole organization,” he wrote.

“That is the real paradox here,” McKee added. “The same architecture that gives defenders scale and simplicity can also give attackers a single point of catastrophic leverage.”

Patch Tuesday - May 2026

12 May 2026 at 20:22

Microsoft is publishing 137 vulnerabilities on May 2026 Patch Tuesday. Microsoft is not aware of exploitation in the wild or public disclosure for any of these vulnerabilities. So far this month, Microsoft has provided patches to address 133 browser vulnerabilities, which are not included in the Patch Tuesday count above.

Windows Netlogon: critical RCE

Anyone responsible for securing a domain controller should prioritize remediation of CVE-2026-41089, which is a critical stack-based buffer overflow in Windows Netlogon with a CVSS v3 base score of 9.8. Exploitation leads to execution in the context of the Netlogon service, so that’s SYSTEM privileges on the domain controller. For most pentesters, that’s the point at which the customer report more or less writes itself. No privileges or user interaction are required, and attack complexity is low, which suggests that creation of a reliable exploit might not be especially difficult for anyone with knowledge of the specific mechanism.

Microsoft assesses exploitation as less likely, but since those exploitability assessments are provided without an accompanying explanation, it’s not clear how much reassurance defenders should take. Anyone who remembers the much-discussed CVE-2020-1472 (aka ZeroLogon) back in 2020 will note that CVE-2026-41089 offers an attacker more immediate control of a domain controller. Patches are available for all versions of Windows Server from 2012 onwards.

Windows DNS Client: critical RCE

An attacker looking for a master key for Windows assets will pay attention to CVE-2026-41096, a critical RCE in the Windows DNS client implementation. A modern computer talks to DNS the way a child in the back of a car asks “are we there yet?” The variable and complex structure of DNS responses means that DNS client implementations are also complex and thus prone to flaws. Microsoft assesses exploitation as less likely, and we can hope that modern mitigations such as heap address randomization and optional-but-recommended encrypted channel DNS will make weaponization significantly more challenging by putting barriers across specific paths to exploitation. The DNS client on Windows runs as the NetworkService role, rather than SYSTEM, but a foothold is a foothold, and skilled attackers expect to chain exploits together.

JIRA/Confluence Entra ID auth plugin: critical EoP

If you’re still self-hosting Atlassian JIRA or Confluence and relying on the Microsoft Entra ID authentication plugin, you’ll want to know about CVE-2026-41103. This critical elevation of privilege vulnerability allows an unauthorized attacker to impersonate an existing user by presenting forged credentials, thus bypassing Entra ID. Microsoft expects that exploitation is more likely. Even if you can’t always find what you want on the corporate Confluence, a motivated attacker probably will. Curiously, the patch links on the advisory lead to older versions of the plugins published in 2024.

Microsoft WARP team

Microsoft’s WARP team is credited with multiple critical vulnerabilities today, after making their first appearance in MSRC advisory acknowledgements in last month’s Patch Tuesday. We can speculate that they likely know a great deal about the current state of AI-powered vulnerability research as it applies to Microsoft products.

Microsoft lifecycle update

There are no significant Microsoft product lifecycle changes this month. Microsoft .NET 9 STS (Standard Term Support, as distinct from Long Term Support) was originally scheduled to move past the end of support in May 2026, but late last year, Microsoft granted a six-month extension, so that .NET 9 STS now reaches end of support on November 10, 2026.

Microsoft addresses 137 vulnerabilities in May’s Patch Tuesday, including 13 rated critical

12 May 2026 at 17:00

Microsoft addressed another triple-digit batch of vulnerabilities cutting across its various enterprise products, components and underlying systems. Yet despite the high number of defects, the vendor reported no actively exploited zero-days in this month’s Patch Tuesday update.

Thirteen of the 137 vulnerabilities Microsoft disclosed were assigned critical CVSS ratings, including a pair of vulnerabilities affecting Azure — CVE-2026-33109 and CVE-2026-42823 — and CVE-2026-42898 in Microsoft Dynamics 365 with 9.9 CVSS scores. 

The company designated 13 vulnerabilities as more likely to be exploited, and 113 defects as less likely or unlikely to be exploited.

The high volume of vulnerabilities reflects a growing trend researchers have been anticipating as artificial intelligence models are deployed to find previously uncovered defects in code. 

While not all of these bugs were found by AI, it’s likely they had an AI-related component — even if it was just AI writing the submission,” Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, wrote in a blog post Tuesday.

Childs was especially intrigued by CVE-2026-41096, which he described as a “nasty-looking bug” in Microsoft Windows DNS that allows unauthorized attackers to run code remotely. 

“No authentication or user interaction needed, and since the DNS Client runs on virtually every Windows machine, the attack surface is enormous. An attacker with a position to influence DNS responses could achieve unauthenticated remote-code execution across your enterprise,” he added. 

Childs also described CVE-2026-41089, a Windows Netlogon defect that allows unauthenticated remote attackers to run code, as the “highest-impact bug that requires immediate patching,” adding that a “compromised domain controller is a compromised domain.”

Jack Bicer, director of vulnerability research at Action1, called out CVE-2026-42898, the critical vulnerability affecting Microsoft Dynamics 365. 

“With no user interaction required, and the potential to impact systems beyond the vulnerable component’s original security scope, this vulnerability poses serious enterprise risk: an attacker with only basic access could turn a business application server into a remote execution platform,” he said in a blog post.

“Compromise of Dynamics 365 infrastructure can expose customer records, operational workflows, financial information, and integrated business systems. Since CRM environments often connect with identity services, databases, and enterprise applications, successful exploitation could lead to broader organizational compromise and operational disruption,” Bicer added.

The full list of vulnerabilities addressed this month is available in Microsoft’s Security Response Center.

Project Glasswing and the Next Challenge for Defenders: Turning Faster Discovery into Faster Action

20 April 2026 at 12:20

Anthropic’s Project Glasswing has sparked plenty of discussion about what AI might soon do for vulnerability discovery, but the more useful question for most security teams is how to prepare for, and more importantly seize the opportunity of, what comes next.

 As we wrote in our earlier blog, What Project Glasswing Means for Security Leaders, AI is becoming more capable of finding software flaws. The pressure that follows lands on the teams responsible for deciding what matters, validating risk, assigning ownership, and getting remediation moving across environments that were already hard to manage. We believe that the organizations that will benefit most from the next wave of AI will be the ones that understand their environment well enough to use these emerging AI models with intent, rather than layering them onto immature processes and hoping that speed alone will solve the backlog.

What this moment means for security teams

The number of publicly tracked software vulnerabilities has broken records almost every year over the last decade, while supply chain risk has continued to rise. Most teams were already feeling the strain of more findings than they could process cleanly. The Common Vulnerabilities and Exposures (CVE) program, the standard system for identifying and tracking known vulnerabilities, recorded 48,185 disclosures in 2025, a 20% increase over 2024, with roughly 40% of those disclosed vulnerabilities rated high or critical. 

The pace in 2026 was already working out to hundreds of new CVEs per day when those figures were cited. That tells you something important about the current environment: the challenge has not necessarily been  a lack of findings, but instead converting a growing stream of findings into measurable risk reduction.

The reality is that very few organizations are going to hand a model free rein over their most sensitive environments the minute those capabilities become more widely available. Trust will be built in stages: early adoption is much more likely to focus on backlog reduction, triage support, patch testing, and repetitive lower-tier remediation work that consumes time without carrying the same level of operational risk as the most critical systems in the business. That is a more realistic starting point, and it leads to a more useful question. Before teams apply AI more broadly, they need to understand their environment well enough to use it intentionally.

Establish the foundation before layering in AI

The promise from Project Glasswing and almost every other AI-powered security initiative is quite similar: leverage AI to identify patterns, summarize risk, suggest fixes, and speed up repetitive work. Regardless of technology, success  still depends on how well an organization understands its environment, the context around each finding, and the process used to act on it. 

A model can generate more output than a team ever could on its own, but that output becomes noise if the organization cannot answer basic questions about scope, ownership, criticality, and exposure. Teams need a clear, continuously updated picture of the environment before they can decide where AI should be applied, what should remain human-led, and which parts of the backlog are safe to push through more automated workflows.

The AI landscape is already shifting fast, and it will keep shifting, which is why this moment should prompt a more preemptive and resilient strategy rather than another round of tooling hype. Chasing each new capability as it arrives will inevitably force teams to keep reorganizing around the latest announcement. A stronger path is to get the foundation right first - understand the environment, the attack paths, and the assets that matter most; but most importantly, establishing the process and the people behind making these decisions. Then use AI where it meaningfully improves speed, consistency, and focus.

Why Attack Surface Management should be part of that foundation

A strong foundation starts with visibility. Security teams need a live picture of what exists in the environment, what is exposed, how assets connect to one another, and which systems carry the greatest business impact if something goes wrong. That is where Attack Surface Management becomes central. Rapid7’s approach through Surface Command is built around a continuous view of the attack surface across the digital estate, which helps teams understand where exposures sit and how they relate to internet-facing, business-critical, or otherwise high-impact systems.

That matters for AI adoption just as much as it matters for day-to-day security operations. Teams cannot apply AI strategically if they are guessing about which parts of the environment are lower priority, which assets belong to which owners, or where a newly disclosed flaw could create real business risk. A better view of the attack surface gives organizations the context they need to segment the problem properly. That makes it far easier to start with the right use cases, whether that is backlog reduction in lower-impact systems, targeted prioritization of exposed assets, or faster triage where the risk picture is already well understood.

Ownership is part of that foundation too. Remediation slows down when no one can quickly identify who owns the affected application, environment, or workflow. Security teams already lose time there today, and AI will only make that bottleneck more visible if it starts surfacing issues faster than organizations can assign them. Attack Surface Management helps turn that ambiguity into something more actionable by tying exposure to environment context and likely ownership.

How Vulnerability and Exposure Management turns visibility into action

Once the environment is understood, teams still need a way to move from findings to outcomes. That is where Vulnerability and Exposure Management becomes the operating layer that keeps the work grounded.

The biggest value here is not simply collecting more vulnerability data. It is targeted prioritization and validation. When a disclosure lands, teams need to know whether the issue affects an exposed asset, whether there is evidence of exploitation or attacker interest, whether the impacted system is business-critical, and whether existing controls already reduce some of the risk. That is the kind of context that helps organizations decide what deserves immediate attention and what can be handled through a normal remediation cycle.

This is where artificial intelligence can help move remediation forward faster. Instead of asking teams to manually connect exploit signals, asset criticality, and vulnerability intelligence on their own, AI can distill that context directly in the remediation workflow. That makes it easier to understand why an issue matters, what the likely impact is, and what to do next, which shortens the gap between discovery and a confident decision on how to respond.

We expect most organizations to use AI to assist with, or in some cases take over, lower-tier triage, backlog cleanup, summary generation, and patch support in areas where the workflow is already established and the blast radius is more manageable. Human experts still stay closest to the most critical business logic, the most sensitive environments, and the most complex remediation paths. That is a practical adoption model, and it only works when the organization already has enough structure in place to know where those boundaries are.

Curated vulnerability intelligence changes the quality of decisions

That kind of deliberate adoption only works when teams can make better decisions, faster. Security teams need more than severity scores and a long list of CVEs. They need enough context to understand what matters, what can wait, and where action will reduce real risk fastest. As Rapid7 outlined in The Power of Curated Vulnerability Intelligence, the goal is to identify the vulnerabilities that actually matter and give teams enough context to act with confidence.

That intelligence provides a form of validation that most teams need badly as disclosure volume rises. It helps answer whether a finding is tied to active attacker interest, whether proof-of-concept activity is public, whether the asset is exposed, and whether delaying a patch creates unacceptable risk. It also supports the decisions that happen in the gap between discovery and full remediation. When a patch is delayed because of change controls, testing constraints, or lack of a vendor fix, teams still need to reduce exposure. Curated intelligence helps them decide whether to use segmentation, access restrictions, configuration changes, added monitoring, or virtual patching while the longer-term fix is being worked through.

That is one of the clearest ways Rapid7 helps customers move from data to outcomes. Intelligence is fused into the workflow so teams can prioritize with more precision and validate their actions against real threat context, not just generalized scores.

How runtime and remediation fit into the broader AI story

There is another part of this story that matters as organizations think more seriously about AI-driven security operations. As AI shapes the way teams handle exposures earlier in the lifecycle, context of application at runtime matters more too.

To make that foundation complete, organizations need to look beyond static posture and bring runtime validation into the picture. When teams can identify which vulnerabilities and misconfigurations are actively exploitable in production, and map sensitive data and identity access to real-world attack paths, they get a much clearer view of actual risk. Security teams need to understand what is vulnerable, how systems behave when live, and where unusual activity may suggest a problem is moving toward exploitation. With that runtime context in place, teams can spend less time chasing theoretical vulnerabilities and more time focusing on the exposures that are actively creating risk in live environments. 

That connection between exposure, intelligence, remediation, and runtime behavior is where AI starts to become genuinely useful rather than simply impressive. It supports a more intentional model of security decision-making, one that narrows the gap between what is found, what matters, and what happens next.

What security leaders should do now

This is a good time for security leaders to step back and ask a more disciplined set of questions.

  • Do we understand our environment well enough to direct AI toward the right problems? 

  • Can we clearly separate higher-risk, higher-impact assets from the parts of the backlog that are mostly operational drag? 

  • Is threat intelligence embedded in how we interpret findings, or are we still depending too heavily on raw severity? 

  • Can we identify ownership fast enough for AI-assisted triage to result in meaningful action? 

  • Are compensating controls part of the plan when remediation cannot happen immediately?

Those questions shape the quality of everything that follows.

Glasswing creates a real opportunity for security teams that are ready to use AI with more intention. AI can move work forward faster, reduce manual drag, and absorb classes of issues that currently consume time without improving outcomes. The teams that benefit most will not be the ones that rush to apply new models everywhere. They will be the ones that understand their environment, have a clear view of their attack surface, have mature enough workflows to apply AI where it makes sense, and can measure whether the actions taken actually reduced exposure.

Rapid7’s approach to building resilience is grounded in those same needs. Attack Surface Management provides the environmental foundation, Vulnerability Management drives prioritization and action, curated vulnerability intelligence strengthens validation and decision-making, AI-generated remediation insights compress the time from discovery to the next step, and runtime security adds context where live behavior matters. Together, those pieces help customers build a security program that is ready for AI rather than constantly reacting to it.

NIST narrows scope of CVE analysis to keep up with rising tide of vulnerabilities

15 April 2026 at 16:17

The federal agency tasked with analyzing security vulnerabilities is overwhelmed as it and other authorities struggle to keep pace with a flood of defects that grows every year. The National Institute of Standards and Technology announced Wednesday that it has capitulated to that deluge and narrowed the priorities for its National Vulnerability Database.

NIST said it will only prioritize analysis for CVEs that appear in the Cybersecurity and Infrastructure Security Agency’s known exploited vulnerabilities catalog, software used in the federal government and critical software defined under Executive Order 14028.

The federal agency’s goal with the change is to achieve long-term sustainability and stabilize the NVD program, which has encountered previous challenges, notably a funding lapse in early 2024 that forced NIST to temporarily stop providing key metadata for many vulnerabilities in the database.

The agency still hasn’t cleared a backlog of unenriched CVEs that built up during that pause and grew since then. 

NIST said it analyzed nearly 42,000 vulnerabilities last year, adding that CVE submissions surged 263% from 2020 to 2025. “We don’t expect this trend to let up anytime soon. Submissions during the first three months of 2026 are nearly one-third higher than the same period last year,” the agency said in a blog post announcing the change. 

Indeed, vulnerabilities are increasing across the board. For instance, Microsoft addressed 165 vulnerabilities Tuesday, its second-largest monthly batch of defects on record.

NIST said CVEs that don’t fit its more narrow criteria will still be listed in the NVD, but they won’t be automatically enriched with additional details. 

“This will allow us to focus on CVEs with the greatest potential for widespread impact,” the agency said. “While CVEs that do not meet these criteria may have a significant impact on affected systems, they generally do not present the same level of systemic risk as those in the prioritized categories.”

Researchers and threat hunters who analyze vulnerabilities for CVE Numbering Authorities (CNA) and vendors that publish their own assessments view NIST’s new approach as inevitable.

“They had to do something. NIST was woefully behind on classifying CVEs and would likely never have caught up,” Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, told CyberScoop.

“I’m not sure if it was a herculean task or a sisyphean one, but either way, they were set up for failure under their previous system. This change allows them to prioritize their work,” he added.

NIST’s new approach will impact the vulnerability research community at large, but also put more private companies and organizations in a position to gain more authority as defenders seek out more alternative sources.

Caitlin Condon, vice president of security research at VulnCheck, previously told CyberScoop that prioritization remains a problem, with too many defenders paying attention to vulnerabilities that aren’t worth their time. 

Of the more than 40,000 newly published vulnerabilities that VulnCheck cataloged last year, only 1% of those defects, just 422, were exploited in the wild

NIST is also trying to reduce other duplicitous efforts with its new approach, effectively leaning even more on CNAs. CVEs that are submitted with a severity rating will no longer receive a separate CVSS score from NIST, the agency said. 

While the agency remains the ultimate authority providing a government-backed catalog of vulnerability assessments, it acknowledged these changes will affect its users.

“This risk-based approach is necessary to manage the current surge in CVE submissions while we work to align our efforts with the needs of the NVD community,” the agency said. “By evolving the NVD to meet today’s challenges, we can ensure that the database remains a reliable, sustainable and publicly available source of information about cybersecurity vulnerabilities.”

Patch Tuesday - April 2026

14 April 2026 at 17:48

Microsoft is publishing 167 vulnerabilities on April 2026 Patch Tuesday. Microsoft is aware of exploitation in the wild for one of today’s vulnerabilities, and public disclosure for one other. Microsoft evaluates 19 of the vulnerabilities published today as more likely to see future exploitation. So far this month, Microsoft has provided patches to address 80 browser vulnerabilities, which are not included in the Patch Tuesday count above.

Increasing volumes of vulnerabilities

Regular Patch Tuesday watchers will know that these vulnerability totals are significantly higher than usual, especially the browser numbers. Late last week, Microsoft published patches to resolve more than 60 browser vulnerabilities in a single day, which is a new record in that very specific category.

A bar chart showing the number of Microsoft browser advisories per day from 2017 to 2026. A significant spike is visible in April 2026.

It might be tempting to imagine that this sudden spike was tied to the buzz around the announcement a week ago today of Project Glasswing, but this is not the case. Edge is based on the Chromium engine, and the Chromium maintainers acknowledge a wide range of researchers for the vulnerabilities which Microsoft republished last Friday. This reflects a significant industry-wide uptick in the volume of vulnerability reports over the past few weeks. A safe conclusion is that this increase in volume is driven by ever-expanding AI capabilities. We should expect to see further increases in vulnerability reporting volume as the impact of AI models extend further, both in terms of capability and availability.

SharePoint: zero-day spoofing

When everything is changing rapidly, it can be tempting to look to familiar things for comfort. SharePoint admins should start by addressing CVE-2026-32201, an exploited-in-the-wild spoofing vulnerability. The advisory doesn’t offer much detail, but does mention CWE-20: Improper Input Validation and low impact to confidentiality and integrity, with no impact to availability. Of course, the greatest attacker impact is typically achieved by chaining together multiple vulnerabilities that by themselves might not seem so bad.

Ever-increasing novel AI capabilities in offensive cybersecurity now appear to provide real competition for all but the most elite human researchers; if it was ever valid to suppose that a vulnerability with a CVSS v3 base score of 6.5 was unlikely to cause much pain, it’s certainly not a safe defensive assumption in 2026. Patches are available for all supported versions of SharePoint, including SharePoint 2016, which moves beyond extended support on July 14, 2026.

Defender: zero-day elevation of privilege

Microsoft Defender receives a patch today for CVE-2026-33825, a local privilege escalation vulnerability for which Microsoft is aware of public disclosure. Successful exploitation leads to SYSTEM privileges, so this is certainly worth patching sooner rather than later. Microsoft points out that no action should be required to install this update, since the Microsoft Defender Antimalware Platform automatically updates by default. A further silver lining is that systems that have disabled Microsoft Defender are not in an exploitable state. Hopefully, any such system is running a suitable third-party replacement for Defender’s capabilities.

Windows [I don’t like] IKE: zero-day pre-auth RCE

The Windows Internet Key Exchange (IKE) Services Extensions is the site of CVE-2026-33824, a critical unauthenticated remote code execution vulnerability. Exploitation requires an attacker to send specially crafted packets to a Windows machine with IKE v2 enabled, which could enable remote code execution. Vulnerabilities leading to unauthenticated RCE against modern Windows assets are relatively rare, or we’d see more wormable vulnerabilities self-propagating across the internet. However, since IKE provides secure tunnel negotiation services, for instance for VPNs, it is necessarily exposed to untrusted networks and reachable in a pre-authorization context. It’s hard to imagine this turning into a rampaging internet-wide worm, but there’s plenty of scope for initial access abuse, so this IKE vulnerability is still yikes.

The advisory does contain a section with potential mitigations for anyone unable to patch immediately, which center on least-privilege restriction of relevant UDP traffic. This same portion of the advisory also furnishes a helpful link to the definition of the word “mitigations” in the MSDN glossary. All versions of Windows back as far as Server 2016 and Windows 10 1607 LTSC receive patches.

The advisory credits both the WARP and MORSE (Microsoft Offensive Research & Security Engineering) teams at Microsoft. MORSE appears in Acknowledgements over the past few years, but today marks the first explicit mention of WARP in a Microsoft security advisory Acknowledgements section; we can speculate that WARP is an internal designator for the Microsoft Windows Enterprise Security Team.

Microsoft lifecycle update

In Microsoft lifecycle news, extended support ends April 14, 2026 for a wide range of Microsoft product legacy enterprise tools, including Dynamics C5 2016, Dynamics NAV 2016, App-V 5.0 and App-V 5.1, UE-V 2.1, and BitLocker Administration and Monitoring 2.5 SP1. Microsoft .NET 9 STS (Standard Term Support, as distinct from Long Term Support) was originally scheduled to move past the end of support in May 2026, but late last year, Microsoft granted a six-month extension, so that .NET 9 STS now reaches end of support on November 10, 2026.

Microsoft drops its second-largest monthly batch of defects on record

14 April 2026 at 16:27

Microsoft addressed 165 vulnerabilities affecting its various products and underlying systems, including one actively exploited vulnerability in Microsoft Office SharePoint, in this month’s Patch Tuesday update

“By my count, this is the second-largest monthly release in Microsoft’s history,” Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, wrote in a blog post Tuesday.

Microsoft didn’t explain why its monthly batch of patches grew so large this month, but Childs noted that many vulnerability programs are experiencing a significant increase in submissions found by artificial intelligence tools. “For us, our incoming rate has essentially tripled, making triage a challenge, to say the least,” he added. 

The zero-day vulnerability — CVE-2026-32201 — has a CVSS rating of 6.5 and allows attackers to view sensitive information and make changes to disclosed information. Microsoft said the improper input validation defect in Microsoft Office SharePoint allows unauthenticated attackers to perform spoofing over a network.

The Cybersecurity and Infrastructure Security Agency added the zero-day to its known exploited vulnerabilities catalog shortly after Microsoft’s disclosure. 

Microsoft also addressed a high-severity vulnerability — CVE-2026-33825 — that was publicly known at the time of release. The vendor said the defect in Microsoft Defender is more likely to be exploited and could allow unauthorized attackers to elevate privileges locally.

“What starts as a foothold can quickly become full system domination,” Jack Bicer, director of vulnerability research at Action1, said in a blog post about the vulnerability. 

“Once exploited, it allows full control over endpoints, enabling data exfiltration, disabling security tools and lateral movement across networks,” Bicer said.

Proof-of-concept exploit code for the defect is publicly available, which increases the likelihood of exploitation in the wild, he added.

Microsoft disclosed two critical vulnerabilities this month — CVE-2026-33824 affecting Windows IKE Extension and CVE-2026-26149 affecting Microsoft Power Apps — but designated both of the defects as less likely to be exploited.

More than three-quarters of the vulnerabilities disclosed this month are less likely to be exploited, according to Microsoft. Meanwhile, the company designated 19 vulnerabilities as more likely to be exploited.

The full list of vulnerabilities addressed this month is available in Microsoft’s Security Response Center.

Negotiating with the Board: Translating Active Risk into Financial Exposure

Security leaders rarely struggle to produce data. The challenge is turning that data into something the board can use to make decisions.

Walk into a board meeting with a slide showing 1,200 critical vulnerabilities and 44 internet-facing assets, and you will likely see polite acknowledgment rather than meaningful discussion. The question that follows tends to cut through quickly: what does this mean for the business?

Boards allocate capital based on financial exposure, not vulnerability counts. A list of findings describes workload, but directors are responsible for revenue protection, liability, and risk to the balance sheet. When security reporting remains technical, it sits outside the way investment decisions are made elsewhere in the organization. The issue is less about communication and more about framing the problem in terms the business already understands.

From severity to risk

CVSS measures theoretical severity, but it does not measure business risk. A high score indicates that a flaw could be dangerous, yet it does not tell you whether the vulnerability is reachable in your environment, whether exploit code exists, or whether it is likely to affect revenue in the near term. It answers a useful engineering question, but it does not answer the question the board is asking.

That question is about likelihood and impact. Most enterprise risk frameworks define risk in those terms, and that is how financial decisions are made. The gap becomes clear when two vulnerabilities appear similar on a dashboard but carry very different consequences. A high-CVSS issue on a segmented lab system may present little business risk, while a moderately severe vulnerability on an internet-facing production system with active exploit activity can expose regulated data and revenue streams.

What is often missing in that comparison is threat context. Understanding how attackers behave, which vulnerabilities they are exploiting, and where access paths actually exist changes how risk is interpreted. Active Risk in InsightVM brings those elements together by combining exploit telemetry, attacker behavior, and asset context to estimate the likelihood that a vulnerability will be used. When that likelihood is paired with business impact, the conversation shifts toward exposure rather than severity.

From CVSS scores to financial exposure

Prioritization alone does not translate into board-level decisions. Knowing what is most likely to be exploited is necessary, but it is not sufficient when the goal is to justify investment.

FAIR provides a way to bridge that gap. The model defines risk as a combination of how often a loss event is likely to occur and how much that event would cost. In practical terms:

Annualized Loss Exposure (ALE) = Loss Event Frequency × Probable Loss Magnitude

Active Risk informs the likelihood side of that equation by grounding it in observed attacker behavior and exploit activity. FAIR converts that likelihood into financial terms, allowing security teams to describe exposure in a way that aligns with how capital is allocated.

Instead of reporting that a set of vulnerabilities is “high risk,” the discussion becomes more concrete. A team might say that a group of issues represents several million dollars in annualized exposure across systems tied to revenue. That is a number that can be evaluated alongside other business risks, rather than interpreted as a technical signal.

A practical example

Consider two vulnerabilities identified during a scan. The first is a CVSS 9.8 issue on a segmented guest Wi-Fi router. It is severe from a technical standpoint, but it has no access to sensitive data, no path into production systems, and no evidence of active exploitation.

The second is a vulnerability with a moderate CVSS score on an internet-facing customer database. Public exploit code exists, and the system stores regulated data tied directly to revenue and compliance obligations.

On a scanner dashboard, the first may appear more urgent. When viewed through a financial lens, the second carries greater risk.

Assume an annual probability of exploitation of 20 percent for the database scenario. If the potential impact includes $750,000 in incident response, $1.2 million from several days of business interruption, $600,000 in legal and regulatory costs, and $1 million in customer churn and reputational damage, the total loss for a single event is $3.55 million.

Applying the FAIR model results in approximately $710,000 in annualized exposure. That figure reflects the risk carried by that single vulnerability on a production system.

By contrast, even if the Wi-Fi router vulnerability had a 5 percent probability of exploitation and a $50,000 impact, the resulting exposure would be around $2,500. Both findings may appear critical in a technical report, but only one represents a material financial concern.

This is where Active Risk and FAIR work together. One identifies where attackers are likely to act, and the other expresses the consequence in financial terms. The combination changes how vulnerabilities are evaluated and how priorities are set.

Visualizing exposure across your environment

Once risk is expressed in financial terms, the next step is to understand how that exposure is distributed. Boards tend to think in terms of portfolios rather than individual issues, and the same principle applies to cybersecurity.

In most environments, exposure is not evenly spread. A relatively small number of systems and vulnerabilities account for a large portion of potential loss. Internet-facing services, systems tied to revenue, and assets with known exploit activity often sit at the higher end of that distribution.

This creates a practical way to focus effort. Rather than attempting to address every vulnerability equally, teams can identify where exposure is concentrated and reduce risk in those areas first. In many cases, addressing a small number of issues can significantly reduce overall exposure, particularly when those issues sit on systems that are both reachable and business-critical.

A before-and-after view helps make this visible. If an organization reduces modeled exposure from several million dollars to a substantially lower figure through targeted remediation, the result can be explained in terms of reduced downside risk rather than increased patching activity. Over time, tracking that change shows whether investments are producing measurable outcomes.

Making risk actionable

By the time exposure is expressed in financial terms, the discussion in the boardroom has already shifted. The focus moves away from counts and severity toward risk, trade-offs, and acceptable levels of exposure.

One of the first issues that arises in that context is the assumption that risk should be driven to zero. In practice, eliminating all exposure is neither achievable nor economically sensible. Reducing risk always involves trade-offs, and those trade-offs become clearer when expressed in financial terms.

If an organization has already reduced exposure significantly, but further reduction requires a disproportionate increase in cost, the decision becomes one of balance. The question is no longer why risk still exists, but whether the remaining exposure aligns with the organization’s tolerance.

The same logic applies when discussing budget. Requests framed in operational terms, such as additional headcount or tooling, are difficult to evaluate in isolation. When those requests are tied to measurable reductions in exposure, the relationship between cost and benefit becomes clearer.

For example, if additional resources reduce several million dollars of modeled exposure at a fraction of that cost, the investment can be assessed alongside other initiatives using the same financial lens. At that point, the discussion is no longer about capacity. It is about risk reduction.

Putting security in business terms

Reducing exposure also affects how the organization is perceived externally. Cyber insurance underwriting, for example, increasingly considers factors such as attack surface, exploit availability, and remediation speed. Demonstrating that exposure is measured and reduced over time can influence how risk is priced.

The same applies during customer due diligence. Being able to explain where risk exists, how it is prioritized, and how it has been reduced provides evidence of maturity. It shows that security is being managed deliberately rather than reactively.

Aligning to risk tolerance

Productive board discussions tend to end with agreement on acceptable levels of exposure. Without a financial view, every issue can appear urgent. With it, prioritization becomes more grounded.

Leadership can evaluate whether the level of risk being carried is consistent with business objectives, and whether further investment is warranted. That shifts vulnerability management from a process focused on volume to one focused on where exposure is concentrated and how it can be reduced most effectively.

Clear exposure, clearer decisions

Vulnerability management has often been treated as an operational activity centered on patching and scanning. When combined with threat context and financial modeling, it becomes part of enterprise risk management.

Instead of reporting how many vulnerabilities exist, security leaders can describe how much exposure the organization carries. Instead of focusing on activity, they can show how targeted actions reduce risk over time. That framing aligns cybersecurity with the same decision-making process used across the rest of the business.

When exposure is clear, decisions become clearer. Leadership can determine where to accept risk, where to transfer it, and where to invest in reduction. The conversation with the board moves away from technical detail and toward measurable impact, which is where security becomes part of strategy rather than an isolated function.

Ubiquiti defect poses account takeover risk for UniFi Networking Application users

20 March 2026 at 12:22

Researchers and threat hunters are scrambling to contain a maximum-severity defect in Ubiquiti’s UniFi Network Application that attackers could exploit to take over user accounts by accessing and manipulating files.

The path-traversal vulnerability — CVE-2026-22557 — affects software used to manage UniFi networking devices, including access points, gateways and switches. The vendor disclosed and released patches for the defect in a security advisory Wednesday.

“As of this morning, we have not observed any public proof-of-concept exploits or confirmed reports of exploitation in the wild,” Matthew Guidry, senior product detection engineer at Censys, told CyberScoop.

“However, because this is a path-traversal vulnerability, the technical complexity for an attacker is typically lower than memory-corruption or buffer-overflow bugs,” he added. “Given that the CVSS 10 rating implies low attack complexity, we anticipate that once the specific vulnerable endpoint is identified, exploitation will be trivial to automate.”

Censys sensors observed nearly 88,000 UniFi Network Application hosts publicly exposed to the internet as of Friday morning. The software doesn’t expose what version it’s running, so scans cannot distinguish between vulnerable and patched instances.

Roughly one-third of the exposed instances of UniFi Network Application are located in the United States. 

As a defender, when you see a CVSS 10 for a product you immediately recognize and know is everywhere, you probably get a bit anxious,” Guidry said. “You also know it’s remotely exploitable, requires no authentication, and needs no user interaction, because it wouldn’t be a 10 if it wasn’t. Ubiquiti is a name you hear frequently, and many of those devices are sitting directly on the internet.”

Ubiquiti advises UniFi Network Application users to update to the latest software versions, which also addressed a second vulnerability — CVE-2026-22558 — that attackers could exploit to escalate privileges.

Cisco’s latest vulnerability spree has a more troubling pattern underneath

18 March 2026 at 17:31

Cisco customers have confronted a flood of actively exploited vulnerabilities affecting the vendor’s network edge software since late February, and researchers say that five of the nine vulnerabilities Cisco disclosed in its firewalls and SD-WAN systems over the past three weeks have already been exploited in the wild. 

Attackers exploited a pair of these defects — zero-day vulnerabilities in Cisco SD-WANs — for at least three years before the vendor and authorities discovered and issued warnings about the threat. Cisco disclosed an additional five SD-WAN vulnerabilities that same day, and three of those defects have since been confirmed actively exploited as well.

Weaknesses lurking in Cisco security products don’t end there. Amazon Threat Intelligence on Wednesday said one of the two max-severity defects Cisco reported in its firewall management software earlier this month has been actively exploited by Interlock ransomware since Jan. 26, more than a month before those vulnerabilities were publicly disclosed.

Some organizations, officials and members of the security community at large have missed widening risks as more of the defects come under attack. The flurry of Cisco SD-WAN and firewall vulnerabilities includes defects with low CVSS ratings, zero-days and others that were determined actively exploited after disclosure.

“These are not random bugs in low-value software. These are management-plane and control-plane weaknesses in devices at the network edge, which often function as trust anchors in enterprise environments,” Douglas McKee, director of vulnerability intelligence at Rapid7, told CyberScoop.

“If you compromise SD-WAN or firewall management, you’re landing on policy, visibility, routing, segmentation, and, in many cases, administrative trust over a large swath of the environment,” he added. “Attackers know that and, when they find a pre-auth path into those systems, especially one that can be chained to root, that’s about as attractive as it gets.”

The full slate of recently disclosed Cisco vulnerabilities affecting these systems include:

Researchers from multiple firms and Cisco have observed or been notified of active exploitation of CVE-2026-20127, CVE-2022-20775, CVE-2026-20122, CVE-2026-20128 and CVE-2026-20131.

The Cybersecurity and Infrastructure Security Agency has only added two of the defects — CVE-2022-20775 and CVE-2026-20127 — to its known exploited vulnerabilities catalog thus far. The agency, which last week added new hunting and reporting requirements to an emergency directive it issued for the defects in late February, did not answer questions about the updated order or explain why other actively exploited Cisco vulnerabilities haven’t been added to the catalog. The agency has been operating under a funding shutdown since February.

Interlock ransomware hits Cisco firewalls

The ongoing ransomware campaign Amazon Threat Intelligence spotted involving CVE-2026-20131 confirmed “Interlock had a zero-day in their hands, giving them a week’s head start to compromise organizations before defenders even knew to look,” researchers said Wednesday.

Interlock’s observed attack path and operations are extensive, including post-compromise reconnaissance scripts, custom remote access trojans, a webshell and legitimate tool abuse. Amazon did not identify specific victims, and said the group threatens organizations with data encryption, regulatory fines and compliance valuations.

“Interlock has historically targeted specific sectors where operational disruption creates maximum pressure for payment,” Amazon Threat Intelligence researchers said in the blog post. These sectors include education, engineering, architecture, construction, manufacturing, industrial, health care and government entities. 

4 Cisco SD-WAN defects under attack

The swarm of vulnerabilities in Cisco SD-WANs poses additional risk for customers. Cisco Talos previously attributed long-running attacks involving CVE-2026-20127 and CVE-2022-20775 to UAT-8616, but it’s unclear if the same threat group is responsible for all of the Cisco SD-WAN exploits. 

“Other threat groups are likely to pick up public research in order to weaponize or adapt it opportunistically, so we may see follow-on attempts by additional threat actors, including low-skilled attackers,” Caitlin Condon, vice president of security research at VulnCheck, told CyberScoop.

Researchers said vulnerabilities are often disclosed in clusters after a meaningful defect is identified in a specific product, such as Cisco’s SD-WAN systems.

Cisco declined to answer questions and said customers can find the latest information on its security advisories page.

Condon and McKee both noted that Cisco has been responsive in releasing software fixes, threat-hunting intelligence and, in the case of the SD-WAN zero-days, coordinated government guidance. 

“This is what a good crisis response is supposed to look like once exploitation is identified,” McKee said. 

“The harder question is whether the industry is getting early-enough visibility into the defects in edge-management software that sophisticated actors are clearly prioritizing,” he added. “Are our organizations equipped with the right people and tools to perform this level of exposure management?”

The expanding exploits Cisco customers are combating on firewalls and SD-WANs is a reminder that organizations shouldn’t deprioritize less notorious vulnerabilities or those with lower CVSS scores, Condon said. 

“Several of the exploited vulnerabilities in this tranche of Cisco SD-WAN bugs don’t have critical CVSS scores, meaning teams using CVSS as a prioritization mechanism might miss medium- or high-scored flaws that still have real-world adversary utility,” she added.

The attacks also collectively reflect a persistent pattern of attackers targeting network edge systems from multiple vendors, including Cisco.

“Attackers continue to treat network edge and management infrastructure as prime real estate, and when defenders see pre-authentication, management-plane flaws with evidence of pre-disclosure exploitation, they need to assume compromise, not just exposure,” McKee said. 

“Attackers are investing time and capability into finding and operationalizing previously unknown defects in Cisco edge and management infrastructure because the payoff is enormous,” he added. “These platforms give you a privileged position, broad visibility, and a path to durable access inside high-value organizations. That’s exactly why they keep getting hit.”

Patch Tuesday - March 2026

10 March 2026 at 16:30

Microsoft is publishing 77 vulnerabilities this March 2026 Patch Tuesday. Microsoft is aware of public disclosure of two of today’s vulnerabilities, but without evidence of exploitation in the wild for any (yet), so there are no Microsoft additions to CISA KEV today. Earlier in the month, Microsoft provided patches to address nine browser vulnerabilities, which are not included in the Patch Tuesday count above.

SQL Server: zero-day remote EoP

SQL Server often goes several months in a row without any mention on Patch Tuesday. Today, however, all versions from the latest and greatest SQL Server 2025 back as far as SQL Server 2016 SP3 receive patches for CVE-2026-21262, a SQL Server elevation of privilege vulnerability. This isn’t just any elevation of privilege vulnerability, either; the advisory notes that an authorized attacker can elevate privileges to sysadmin over a network. The CVSS v3 base score of 8.8 is just below the threshold for critical severity, since low-level privileges are required.

Microsoft is aware of public disclosure, so while they assess the likelihood of exploitation as less likely, it would be a courageous defender who shrugged and deferred the patches for this one. Most SQL Server admins and security teams concluded many years ago that exposing SQL Server directly to the internet was not a good idea. Then again, popular search engines for internet-connected devices describe tens of thousands of SQL Server instances, and they can’t all be honeypots.

What could an attacker do as SQL Server sysadmin? Beyond exfiltrating or interfering with the database itself, the obvious target is xp_cmdshell, which allows direct callouts to the underlying OS. The good news is that xp_cmdshell is disabled by default as far back as SQL Server 2005; the bad news is that anyone acting as SQL Server sysadmin can enable it in seconds. At that point, the attacker is acting with the full privileges of the security context under which SQL Server runs, which is ideally a purpose-built account designed with least privilege in mind. If you want to hear some hair-raising stories, you have only to ask any incident response veteran if they’ve ever seen it set up differently.

Anyone paying for Extended Security Updates (ESU) for SQL Server 2014 or SQL Server 2012 may be forgiven for wondering why there’s no security update for those venerable versions of the world’s most widely deployed closed-source database product. We can hope that the vulnerability described by CVE-2026-21262 was introduced in newer codebases only.

.NET: zero-day DoS

Attackers fond of low-effort denial of service attacks against .NET applications will be checking out CVE-2026-26127 today. Microsoft is aware of public disclosure. While the immediate impact of exploitation is likely contained to denial of service by triggering a crash, opportunities for other types of attacks might emerge during a service reboot. Alternatively, if a log forwarder or security agent is impacted, even for a brief period of time, an attacker might carry out an attack in that moment hoping to evade detection under cover of this artificial darkness. Even if a low-skilled attacker simply causes downtime, in some contexts that could be enough to cause an SLA breach or loss of revenue, or at the very least cause a bleary-eyed defender to get paged in the middle of the night.

Authenticator: QR code impersonation

Microsoft Authenticator mobile app users on both iOS and Android should update to the latest version to prevent exploitation of CVE-2026-26123, which involves a malicious app disguising itself as Microsoft Authenticator. Exploitation succeeds when the malicious app receives enough information to impersonate the user.

Authenticator-type apps are often installed on a personal device, but it's not unusual for them to provide multi-factor authentication (MFA) codes for production services in a bring-your-own-device context. This is as good a time as any for defenders to consider how well their mobile device management policy covers app choice enforcement and patching for MFA apps.

The CVSS v3 base score of 5.5 might appear unremarkable, and exploitation requires user interaction, since the user must install the malicious app in the first place. However, exploitation could begin via an attacker-controlled link, or even a malicious QR code that drives users to the malicious app, and a motivated attacker with a physical presence near the user base might well consider this option.

According to Khaled Mohamed, the researcher who discovered this vulnerability, the legitimate Microsoft Authenticator app did not previously register itself as the handler for deep links into its own custom URL scheme. A malicious app could exploit this gap by simply registering itself as the default handler. He further notes that in this scenario, a user of a mobile device with a malicious app installed only needs to click a generic “Open link” dialog, rather than expressly selecting the malicious app each time. This means that the Microsoft advisory is perhaps too optimistic about how much user interaction is required to trigger exploitation.

Microsoft ranks this vulnerability as important on their proprietary severity scale. The advisory also provides a brief peek behind the curtain, since the executive summary notes that “Cwe is not in rca”. The weakness listed on the advisory is CWE-939: Improper Authorization in Handler for Custom URL Scheme.

Microsoft lifecycle update

There are no significant Microsoft product lifecycle changes this month, unless you are responsible for a Microsoft SQL Server 2012 Parallel Data Warehouse instance, which moves beyond extended support as of March 31st. It would be wise not to count on a last-minute extension, since Microsoft has already granted a six month reprieve.

Update history

  • 2026-03-16: updated section on CVE-2026-26123 to include researcher commentary.

Microsoft’s monthly Patch Tuesday is first in 6 months with no actively exploited zero-days

10 March 2026 at 15:37

Microsoft addressed 83 vulnerabilities that cut across its broad portfolio of enterprise software and underlying services in its latest security update. The company’s Patch Tuesday release contained no actively exploited zero-day vulnerabilities and six defects it described as more likely to be exploited. 

The vendor’s batch of patches marks the first monthly update without an actively exploited zero-day in six months.

The “lack of bugs under active attack is a nice change from last month,” when Microsoft reported six actively exploited vulnerabilities, Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, said in a blog post Tuesday. 

Two vulnerabilities addressed this month — CVE-2026-21262 and CVE-2026-26127 — were listed as publicly known at the time of release. “These bugs are more bark than bite,” said Satnam Narang, senior staff research engineer at Tenable. 

More than half of the defects in this month’s update can trigger escalated privileges, and six of those vulnerabilities — CVE-2026-23668, CVE-2026-24289, CVE-2026-24291, CVE-2026-24294, CVE-2026-25187 and CVE-2026-26132 — were rated as more likely to be exploited, Narang added.

An information-disclosure defect in Microsoft Excel — CVE-2026-26144 — showcases an attack scenario that’s likely to occur more often, according to Childs. “An attacker could use it to cause the Copilot Agent to exfiltrate data off the target,” essentially making it a zero-click operation, he wrote.

Researchers also focused on a pair of defects in Microsoft Office with CVSS ratings of 8.4 — CVE-2026-26110 and CVE-2026-26113 — that attackers can trigger to execute arbitrary code. The preview plane in Microsoft Office can serve as the attack vector for both vulnerabilities.

“Remote-code execution vulnerabilities in Office applications pose significant risks for organizations, as documents are widely shared via email, file shares, and collaboration platforms,” Mike Walters, president and co-founder of Action1, said in an email. 

“If exploited, attackers could gain control of user systems, deploy ransomware, steal corporate data, or move laterally across internal networks,” he added. “Even a single malicious document could compromise an endpoint and give attackers a foothold inside the organization.”

The full list of vulnerabilities addressed this month is available in Microsoft’s Security Response Center.

The post Microsoft’s monthly Patch Tuesday is first in 6 months with no actively exploited zero-days appeared first on CyberScoop.
