TL;DR
Microsoft’s November 10, 2026, security release lists 1,094 Microsoft CVEs, following 1,474 in October. One Outlook vulnerability was exploited before a fix was available, while a separate Paint vulnerability has had a reported versioning problem. Microsoft has not said how many November fixes were found with AI.
Microsoft’s November 10, 2026, security release lists 1,094 Microsoft CVEs, including an Outlook vulnerability that Microsoft says was exploited before it was fixed. The release follows a record-scale month in October, when the company listed 1,474 CVEs, and comes as users are also contending with reports that a separate Paint security fix may not yet be reaching everyone.
Microsoft’s Security Update Guide describes the November release as consisting of 1,094 Microsoft CVEs. Krebs on Security counted 1,093 flaws published on November 10; the source material attributes the one-item difference to CVE-2026-109469, a Critical Entra Device Registration flaw published on November 5. Microsoft’s data also includes entries from other software makers, but the reported 1,094 figure is based on Microsoft-issued vulnerabilities rather than those third-party entries.
The most urgent item identified in the source is CVE-2026-124194 in Outlook. Microsoft rates it Moderate, with a CVSS score of 6.5, but marks it as having “Exploitation Detected.” The flaw can expose a user’s NTLMv2 password hash when the user opens a crafted file, according to the source material. The U.S. Cybersecurity and Infrastructure Security Agency added it to its list of exploited vulnerabilities on November 10.
A separate issue concerns CVE-2026-83844 in Paint, published on October 13. Heise reported that the version Microsoft initially identified as fixed remained vulnerable. The source says Microsoft named version 11.2609.401.0 as the working version on November 6, while PC Gamer reported that the update was still not appearing for some users. These Paint reports are distinct from the November CVE total and should not be confused with the Outlook flaw.
November’s Patch Load and Two Key Risks
Microsoft listed 1,094 CVEs in its November release. An exploited Outlook flaw needs attention, while reports leave the separate Paint fix’s availability uncertain.
Prioritize the exploited Outlook flaw
CVE-2026-124194 was exploited before a fix was available, despite its Moderate rating.
Check which Outlook and Office products your organization runs.
Use Microsoft’s Security Update Guide and your deployment policies.
Confirm the relevant updates reached affected systems.
The release spans many products
The headline total is not one patch for every device; teams need to match fixes to the software they use.
Keep the Paint issue separate
Reports concern CVE-2026-83844, published October 13, and uncertainty about whether the fix is reaching everyone.
- Microsoft identified version 11.2609.401.0 as working on November 6.
- Users can check the Microsoft Store and verify their installed version.
- Reports say the update was missing for some users.
- The supplied material does not establish availability for everyone.
Read the totals with care
The monthly figures count listed CVEs, not separate updates or flaws all being exploited.
| Count | What it represents |
|---|---|
| 1,094 | Microsoft’s November release-note total |
| 1,093 | Krebs on Security’s November 10 count; the source attributes the difference to a CVE published November 5 |
| 24 | November 10 CVEs credited to researchers using an AI model; this does not show Microsoft’s internal AI contribution |
Outlook Risk and a Growing Patch Load
The release combines a large volume of fixes with a clear priority for administrators: the exploited Outlook vulnerability deserves prompt attention, even though its Moderate rating is below the severity assigned to some other issues. A severity score is one part of prioritization; evidence that attackers are already exploiting a flaw can change how quickly organizations choose to deploy a patch.
The scale also affects how security teams plan testing and deployment. Microsoft’s product breakdown assigns 726 CVEs to Windows and 174 to Office, with additional issues affecting SQL Server, developer tools, SharePoint Server, Azure and other products. Organizations will need to identify which products they run and apply relevant updates, rather than treating the headline total as a single patch for every device.
For individual users, the reported Paint version problem is a reminder to check whether an application update actually arrived. The source recommends addressing Outlook and Office updates first, then reviewing relevant Critical server fixes and checking Paint separately through the Microsoft Store. That is a source-based prioritization suggestion, not a substitute for an organization’s own security procedures.

How Microsoft Explains the Counts
The November figure is part of a sharp rise in the company’s monthly release-note counts. The source’s review of Microsoft data lists 63 CVEs in November 2025, 220 in June 2026, 663 in July, 999 in September and 1,474 in October. The November 2026 total is 1,094. These counts describe listed CVEs, not necessarily the number of separate software updates or the number of vulnerabilities that are being exploited.
Microsoft has said that improved discovery methods contribute to larger releases. In an April post, Tom Gallagher, vice president of engineering at the Microsoft Security Response Center, wrote that AI “can discover more issues, more quickly, across a broader surface area than previous methods.” In May, Gallagher said “Advanced AI models are part of the discovery picture and help to accelerate it,” while also pointing to automation and broader participation by outside researchers. Microsoft said it expected releases “to continue trending larger for some time.”
The November data does not establish how much AI contributed to the total. The source reports that 24 of 1,093 CVEs published on November 10 credit researchers using an AI model, but researcher credit lines do not reveal the tools Microsoft used internally. The count is therefore evidence of a large release, not a measure of AI’s share in finding or fixing the vulnerabilities.
“This release consists of 1094 Microsoft CVEs”
— Microsoft Security Update Guide, November 2026 release notes
Microsoft has not disclosed how many of the November vulnerabilities were found with AI, internally or by outside researchers. The 24 AI-related researcher credit lines cited in the source cannot answer that question, because credit details do not show Microsoft’s internal discovery methods. It is also unclear from the supplied material whether all affected organizations have deployed the Outlook fix.
The Paint reports leave unresolved whether version 11.2609.401.0 is available to all users and whether it fully addresses CVE-2026-83844 on every affected installation. Heise and PC Gamer are cited for the reported problems, but the source provides no direct Microsoft statement resolving them. The precise relationship between the earlier vulnerable version and later distribution issues is not fully established in the material.
The monthly totals also require care in interpretation. The 1,094 release-note count differs from Krebs on Security’s 1,093 November 10 count because of a CVE published earlier, according to the source. Neither figure indicates that all listed flaws are equally severe or actively exploited; Microsoft’s data identifies one November release flaw as exploited.
Patch Deployment and Store Checks
Organizations should review Microsoft’s Security Update Guide against their installed products and deployment policies, giving particular attention to CVE-2026-124194 in Outlook. Administrators should also assess the Critical server vulnerabilities relevant to their environments and confirm that fixes have been installed, rather than relying only on the release’s overall count.
Users concerned about the Paint issue can check the Microsoft Store for the version identified in the source, 11.2609.401.0, and verify the installed version. The supplied reporting does not establish when distribution will reach every user or whether Microsoft plans another correction.
Further clarity may come from updated Microsoft release notes, security guidance or statements about the Paint package. The next monthly security release will also show whether the high CVE counts continue, but the source material gives no confirmed date-specific forecast beyond Microsoft’s statement that releases may remain larger for some time.
