TL;DR
Microsoft’s November 10, 2026, security release lists 1,094 Microsoft CVEs, including an Outlook vulnerability that was exploited before a fix was available. A separate Paint flaw has its own patch history: the initially identified version reportedly remained vulnerable, and some users still cannot see the later version Microsoft named as fixed.
Microsoft’s November 10, 2026, security release lists 1,094 Microsoft CVEs, including an Outlook flaw exploited before a fix was issued. Separately, a Paint vulnerability has prompted questions about whether the version Microsoft first identified as fixed was safe and whether the later version is reaching users.
The Microsoft Security Update Guide release notes describe the November release as consisting of 1,094 Microsoft CVEs. Krebs on Security counted 1,093 flaws first published on November 10; the one-entry difference is CVE-2026-109469, a Critical Entra Device Registration flaw published on November 5. Microsoft says no customer action is needed for that issue. The source’s review of Microsoft’s data says the release’s total excludes vulnerabilities issued by other vendors.
The most urgent item identified in the supplied material is CVE-2026-124194 in Outlook. Microsoft rates it Moderate, with a CVSS score of 6.5, and marks it as having detected exploitation. The vulnerability can expose a user’s NTLMv2 password hash when the user opens a crafted file, according to the source. The U.S. Cybersecurity and Infrastructure Security Agency added the flaw to its catalog of known exploited vulnerabilities on November 10.
The Paint issue is separate from the November release. CVE-2026-83844 was published October 13; the source says heise reported that the version Microsoft initially named as fixed remained vulnerable. Microsoft named version 11.2609.401.0 on November 6, but PC Gamer reported that the update was still not appearing for some users. The supplied material advises checking Paint through the Microsoft Store, rather than treating the Paint update as part of the 1,094-CVE release.
Microsoft’s November fixes and Paint’s separate patch
The November release lists 1,094 Microsoft CVEs. An exploited Outlook flaw needs attention, while Paint’s fix has separate version and availability questions.
Prioritize the exploited Outlook flaw
CVE-2026-124194 is marked as exploited; opening a crafted file can expose a user’s NTLMv2 password hash.
Check Microsoft guidance and identify affected systems.
Assess Critical server vulnerabilities against your environment.
Apply relevant updates using your testing and deployment process.
The release count has limits
A CVE total does not show how many attacks occurred or how severe the full set is.
- Microsoft listed 1,094 CVEs.
- The Outlook flaw is marked exploited.
- Windows accounts for 726 CVEs; Office for 174.
- How many users or organizations were affected.
- How much AI contributed to discovery.
- Which threat actors were involved.
Paint follows a separate patch path
The Paint vulnerability is not part of the November CVE release.
Prioritize Outlook and Paint Updates
The release count is unusually large relative to the figures cited for the same month a year earlier, but the total alone does not tell users which fixes present the most immediate risk. The Outlook flaw is marked exploited, making it a practical priority for organizations and individuals using affected software. Microsoft rates it Moderate; that rating does not negate the separate indication that attackers have used it.
Administrators also need to identify which fixes apply to their systems. The source’s product breakdown assigns 726 CVEs to Windows, 174 to Office, 59 to SQL Server, and smaller counts to other product families. That spread makes a blanket instruction to install every update at once less useful than checking the relevant Microsoft guidance, prioritizing the exploited Outlook issue, and then reviewing Critical server fixes that affect the organization’s environment.
Paint raises a different, user-facing concern: a fix may be described by version yet not be available to every user. The reported gap between Microsoft’s version reference and what some users can see means people may need to check the Store and verify the installed version, rather than assume the application updated automatically.

How the Patch Count Grew
The source’s review of Microsoft’s monthly release notes shows 63 Microsoft CVEs in November 2025, followed by 65 in December. It reports 220 in June 2026, 663 in July, 999 in September, and 1,474 in October. November’s 1,094 is therefore a large release, though below October’s figure. These counts refer to listed CVEs, not a measure of how many attacks occurred or how severe the full set is.
Microsoft has said that artificial intelligence contributes to vulnerability discovery, alongside more mature automation and greater participation by outside researchers. In a May post, Microsoft Security Response Center engineering vice president Tom Gallagher said advanced AI models were “part of the discovery picture” and that releases were expected “to continue trending larger for some time.” The source counts 24 November entries with researcher credits that mention an AI model, but those credit lines do not establish how much AI Microsoft used internally.
The Paint vulnerability follows its own timeline. It was published nearly a month before the November Patch Tuesday release, and the version Microsoft later identified as fixed was reported to be missing for some users. It should not be conflated with the November CVE count or assumed to have been delivered through the same update process.
“This release consists of 1094 Microsoft CVEs.”

What the Counts Cannot Show
Microsoft has not said how many of November’s vulnerabilities were discovered using AI, and researcher credit lines cannot reveal the tools used inside the company. The supplied source identifies 24 entries with AI-related credits, but that is not a reliable count of AI’s overall contribution. Nor does the number of CVEs by itself measure the release’s risk to a particular organization.
The source reports that the Outlook vulnerability was exploited and that CISA added it to its exploited-flaw catalog. The supplied material does not give details about the number of victims, the scope of attacks, or which threat actors were involved. For Paint, it remains unclear from the material how many users cannot access version 11.2609.401.0, when broader availability will occur, or whether Microsoft has confirmed the reported behavior affecting the earlier version.
The source’s recommended ordering—to patch Outlook and Office first, then relevant Critical server flaws—is practical guidance, not a substitute for Microsoft’s product-specific notices. Exact exposure and remediation steps depend on installed software and configuration.
Check Updates and Version Status
Organizations should review Microsoft’s November security guidance and identify affected products, with CVE-2026-124194 in Outlook at the top of the supplied source’s priority list. Administrators should then assess the Critical server vulnerabilities against the software and systems they operate, and apply the relevant updates under their established testing and deployment procedures.
Paint users can check the Microsoft Store for the application update and confirm whether the installed version is 11.2609.401.0. Microsoft has not provided, in the supplied material, a date by which that version should be available to everyone. Further information about rollout availability or the reported problem with the earlier version would clarify whether users need to take additional steps.
Key Questions
How many CVEs are listed in Microsoft’s November 2026 release?
Microsoft’s release notes list 1,094 Microsoft CVEs. Krebs on Security counted 1,093 first published on November 10; the difference is one Entra Device Registration flaw published five days earlier.
Which November vulnerability does the source identify as exploited?
CVE-2026-124194 in Outlook is marked as having detected exploitation. The source says opening a crafted file can expose a user’s NTLMv2 password hash and notes that CISA added it to its exploited-flaw catalog on November 10.
Is the Paint flaw part of the 1,094-CVE release?
No. CVE-2026-83844 was published on October 13 and is discussed as a separate Paint update issue, not as part of the November 10 release count.
What Paint version did Microsoft identify as fixed?
The source says Microsoft named Paint version 11.2609.401.0 on November 6. PC Gamer reported that the version was still unavailable to some users; the supplied material does not state when rollout will reach everyone.
Does Microsoft say AI caused all the November fixes?
No. Microsoft has described AI as one part of vulnerability discovery and has also cited automation and outside researchers. It has not said how many of November’s fixes came from AI.
