TL;DR
Microsoft’s November 10, 2026, Patch Tuesday release notes list 1,094 Microsoft CVEs, including an Outlook vulnerability marked as exploited before a fix was available. A separate Paint flaw has a reported fix-version problem, and some users reportedly still cannot access the working update.
Microsoft’s November 10, 2026, Patch Tuesday release lists 1,094 Microsoft CVEs, including an Outlook vulnerability Microsoft says was exploited before it was fixed. The release is the second consecutive four-digit monthly total, while a separate Paint security flaw has prompted reports that the initially named fixed version remained vulnerable and that the later working version is not available to every user.
Microsoft’s Security Update Guide says the November release consists of 1,094 Microsoft CVEs. The supplied account says Krebs on Security counted 1,093 flaws published on November 10; the one-count difference is CVE-2026-109469, an Entra Device Registration issue published five days earlier. Microsoft says no customer action is needed for that flaw. The release follows an October total of 1,474, according to the same source material.
The most urgent item identified in the November release is CVE-2026-124194 in Outlook. Microsoft rates it Moderate, with a CVSS score of 6.5, but marks it as having detected exploitation. The source says a crafted file can expose a user’s NTLMv2 password hash and that the U.S. Cybersecurity and Infrastructure Security Agency added the flaw to its catalog of exploited vulnerabilities on November 10. The supplied material does not include Microsoft’s full advisory or specific mitigation instructions.
A different issue concerns Microsoft Paint vulnerability CVE-2026-83844, published October 13. According to heise, the version Microsoft first identified as fixed remained vulnerable. Microsoft named version 11.2609.401.0 as the working version on November 6, while PC Gamer reported that some users still could not see that version. The account advises users to check Paint updates through the Microsoft Store, but does not establish how many installations remain affected.
November Patch Tuesday What to prioritize
Microsoft listed 1,094 CVEs in its November 10 release. The exploited Outlook flaw warrants priority, while reports raise questions about Paint’s working update.
Prioritize the exploited Outlook flaw
CVE-2026-124194 is marked as exploited; Microsoft rates it Moderate.
Identify Outlook and Office systems in use.
Check Microsoft advisories and prioritize the Outlook update.
Review applicable Critical server flaws against your systems.
A large count needs context
The monthly total covers fixes across a broad product range; it does not mean every flaw has the same immediate risk.
- Windows, Office and SQL Server
- Developer tools and SharePoint Server
- Azure and Exchange Server
- One November flaw was marked exploited
- Monthly exploited counts stayed between zero and six in the period reviewed
- CVE totals do not measure every attack
Check the Paint fix
Reports say the first version named as fixed for CVE-2026-83844 remained vulnerable.
| Paint update | Reported status | Reader action |
|---|---|---|
| Version 11.2609.401.0 | Named as working on November 6 | Check Microsoft Store and verify the installed version |
Prior Exploitation Raises Outlook Priority
The headline count signals a large patching workload, but it does not mean every listed CVE presents the same immediate risk. The Outlook issue stands out because Microsoft marked it as exploited, and CISA’s addition of the vulnerability to its exploited-flaws list gives security teams a specific reason to review exposure and prioritize the relevant update.
The source’s month-by-month review says the number of Microsoft CVEs rose from 63 in November 2025 to 1,094 in November 2026. It also says monthly counts of flaws marked exploited stayed between zero and six over the period reviewed, with one in November. That distinction matters: a growing number of disclosed fixes does not, by itself, show that attacks are increasing at the same pace. The figures describe the source’s tally of Microsoft’s published data, not a measure of every attack or vulnerability in use.
For organizations, the release spans products including Windows, Office, SQL Server, developer tools, SharePoint Server, Azure and Exchange Server. Administrators need to identify which products they run and apply updates based on exposure and Microsoft’s advisories. The supplied source recommends prioritizing Outlook and Office, then reviewing applicable Critical server flaws, while checking Paint separately.

Microsoft’s Expanding Monthly CVE Counts
The November figure comes from Microsoft’s Security Update Guide release notes and data files, rather than a count limited to flaws disclosed for the first time that day. The source says the November machine-readable file contains 1,342 entries, including 247 attributed to other vendors, mostly Chrome issues also relevant to Microsoft Edge. After excluding other vendors’ entries and one Edge entry, it says the count matches the 1,094 Microsoft CVEs in the release notes.
Microsoft has described several reasons its monthly releases may be growing. In an April post, Tom Gallagher, a vice president of engineering at the Microsoft Security Response Center, said AI can help find more issues more quickly across a broader range of products. In May, he said advanced AI models are part of vulnerability discovery, while also citing more mature automation and wider participation by outside researchers. Microsoft said it expects releases to continue trending larger for some time and that it is not changing its bug bar.
The source material reports that 24 November entries credit researchers who used an AI model: 23 cite GLM from z.ai and one cites Claude. It says the credit line for the exploited Outlook flaw names Benoît Sevens using Claude with Anthropic, as well as a second researcher identified as “nono.” Those acknowledgments concern credited research; they do not establish how much AI contributed to Microsoft’s internal discovery or to the overall count.
“This release consists of 1094 Microsoft CVEs.”

Paint Fix Availability Remains Unclear
The source material does not establish how many users still have a vulnerable Paint version, whether the reported Store availability issue affects all regions or devices, or when the update will appear for those users. Microsoft’s complete advisory and any guidance for installations that cannot yet access version 11.2609.401.0 are not included.
The source also does not provide the complete Outlook advisory text or detail the conditions needed for exploitation. Its description says a crafted file can expose an NTLMv2 password hash, but readers should consult Microsoft’s advisory for the precise affected versions, attack requirements and available mitigations. The number of CVEs attributed to AI-assisted research does not reveal Microsoft’s internal use of AI or the share of the release found with those tools.
Apply Updates and Check Paint
Organizations should review Microsoft’s November advisories and their own software inventories, then prioritize the Outlook update because the flaw is marked as exploited. They should also assess relevant Office and server updates against their systems and Microsoft’s severity ratings rather than treating the total CVE count as a single risk level.
Users and administrators can check the Microsoft Store for the Paint version identified in the reports, 11.2609.401.0, and verify that the installed version has updated. Further clarity depends on Microsoft’s product guidance and on whether the reported Paint update reaches affected users. The available source material does not identify a later deadline or a further Microsoft announcement.
