Microsoft Paint RCE Fix Now Available, but Windows Update Won't Deliver It

Summary: A remote code execution flaw in Windows Paint, CVE-2026-83844, is fixed only in Microsoft Store build 11.2609.401.0, not through Windows Update; Microsoft rates it Important with a CVSS score of 8.1 and says exploitation requires a deep understanding of the target system. The CVE record and NVD entry still list Paint as affected only below 11.2605.91.0, while the advisory names 11.2609.401.0 as the fixed build, and researcher Brian Vitko of RFF found the Store offering 11.2605.81.0 in six countries earlier this week.
Bottom line: A scanner reading the CVE record will treat any build from 11.2605.91.0 up as fixed, so machines running builds between that and 11.2609.401.0 can pass a check while still carrying the flaw. Paint is installed per user account and Windows can keep a provisioned copy, so checking only the signed-in account can miss older copies.
