TL;DR
Microsoft’s November 10, 2026, security release lists 1,094 Microsoft CVEs, up from 63 on the same release-notes page a year earlier. One Outlook flaw is marked as exploited; separately, reporting says a Paint version Microsoft identified as fixed remained vulnerable, with the working update not yet available to some users.
Microsoft’s November 10, 2026, security release lists 1,094 Microsoft CVEs, including an Outlook flaw the company marks as exploited before a fix was available. Separately, heise and PC Gamer reported a problem with the fix for a Paint vulnerability: the initially named version remained vulnerable, and some users still could not access the later version identified as working.
The figure is unusually high compared with the same month’s release notes a year earlier, which listed 63 Microsoft CVEs. Microsoft’s October 2026 release listed 1,474. Security reporter Brian Krebs counted 1,093 fixes published on November 10; the one-item difference reflects a cloud flaw Microsoft had published five days earlier. The source’s review of Microsoft’s data says the total concerns Microsoft-issued CVEs, rather than a count padded with flaws from other vendors.
The most time-sensitive item is CVE-2026-124194, a Microsoft Outlook spoofing vulnerability rated Moderate, with a CVSS score of 6.5. Microsoft marked it as having detected exploitation; the source reports that opening a crafted file can expose a user’s NTLMv2 password hash. The Cybersecurity and Infrastructure Security Agency added the flaw to its list of exploited vulnerabilities on November 10. The supplied material does not include Microsoft’s full technical description or a complete account of affected versions.
The separate Paint flaw, CVE-2026-83844, was published October 13. According to heise, the Paint version Microsoft first identified as fixed remained vulnerable. The source says Microsoft identified version 11.2609.401.0 as working on November 6, while PC Gamer reported that the update was still not appearing for some users. This Paint issue is separate from the November Patch Tuesday CVE total and should be checked through the Microsoft Store.
Microsoft’s November Patch Tuesday 1,094 CVEs and a Paint issue
Microsoft listed an unusually high number of fixes. An exploited Outlook flaw and reports of a delayed Paint fix need focused attention.
Prioritize Outlook
Exploitation status matters alongside severity when deciding what to address first.
Outlook spoofing flaw
CVE-2026-124194 is rated Moderate, with a CVSS score of 6.5. Microsoft says it detected exploitation.
Paint fix availability
Reports say the initially identified version remained vulnerable, and some users could not access the later working version.
What the total counts
The release-note figure counts Microsoft-issued CVEs; it is not a measure of attacks or affected customers.
- 1,094 Microsoft CVEs
- Includes one cloud flaw published five days earlier
- Brian Krebs counted 1,093 fixes published that day
- The one-item difference is the earlier cloud flaw

Prioritize Outlook and Paint Updates
The size of the release creates a substantial workload for organizations that must test and deploy security updates across many systems. But the raw total does not by itself indicate that every flaw poses the same level of immediate risk. The Outlook vulnerability stands out because Microsoft marks it as exploited, even though its severity rating is Moderate; security teams may need to weigh exploitation status alongside severity and the systems they operate.
The separate Paint reports show why installation status matters as much as a vendor’s announcement that a fix exists. If the initially named version remained vulnerable, and the later version is not reaching every user, some devices may still need attention. The source advises users to patch Outlook and Office first, then review relevant Critical server fixes and check Paint separately through the Store. That is a prioritization suggestion, not a replacement for Microsoft’s guidance for specific products and environments.
The rising count also matters for how readers interpret Patch Tuesday totals. Microsoft’s own explanation includes improved discovery methods, automation and outside research, with AI among the factors. A higher count can reflect more vulnerabilities being found and fixed; it does not establish that attacks have risen at the same rate. In the November data examined by the source, monthly exploited counts remained between zero and six, with one in this release.

How the November Total Was Counted
Microsoft’s release notes state that the November release consists of 1,094 Microsoft CVEs. The source writer says Microsoft’s machine-readable Security Update Guide data file contains 1,342 entries, including 247 attributed to other vendors, most commonly Chrome-related issues also relevant to Edge. Of the entries naming Microsoft as issuer, one Edge entry is excluded from the release-note total. The resulting count aligns with Microsoft’s 1,094 figure. Krebs’ 1,093 count covers items first published on November 10; the extra entry is CVE-2026-109469, a Critical Entra Device Registration flaw published November 5, for which Microsoft says no customer action is required.
The month-to-month figures cited in the source are 63 in November 2025, 65 in December 2025, 220 in June 2026, 663 in July, 999 in September and 1,474 in October. These are counts from Microsoft’s release information, not a measure of successful attacks or of the number of affected customers. The source also reports 5,523 Microsoft CVEs from January through November 2026 under its counting method; Krebs separately described the year’s patch count as more than 5,100, using a different method.
Microsoft has linked larger releases to changes in vulnerability discovery. In an April post, MSRC engineering vice president Tom Gallagher said AI can help identify issues across a broader surface area and that Microsoft expected to find a greater volume and diversity of vulnerabilities. In May, Microsoft said advanced AI models were part of the discovery process, alongside more mature automation and wider participation by outside researchers. It also said it expected releases to remain larger for some time. The company has not said how many of November’s fixes came from AI.

The supplied information does not establish how many November vulnerabilities were found with AI. The source writer counted 24 November 10 entries whose credit lines mention researchers using an AI model—23 citing GLM from z.ai and one citing Claude—but those credits do not reveal Microsoft’s internal tools or the full role AI played. They cannot be treated as a complete tally of AI-assisted discoveries.
There is also a discrepancy between the Outlook flaw’s moderate rating and its exploitation status, but the source does not provide details about the attacks, their reach, or the number of affected users. For Paint, the reports do not establish how many users lack version 11.2609.401.0, which distribution issue is responsible, or when all users will receive it. Microsoft’s full response to the reported Paint-version problem is not included in the material.
Check Microsoft’s Fix Guidance
Organizations should consult Microsoft’s security guidance for the affected products, prioritize the exploited Outlook vulnerability, and deploy other updates according to their exposure and testing requirements. Administrators should review the Critical server flaws relevant to their own networks rather than assuming every listed CVE affects every environment.
Paint users can check the Microsoft Store for version 11.2609.401.0, the version the source identifies as working, and verify that the update has installed. Microsoft may provide further clarification or distribution updates; the supplied material does not give a date for broader availability. The next security release and any subsequent correction to the Paint guidance will show whether the unusually high patch counts and the reported app-update problem continue.
