Senserva AI Opinion for CVE-2025-49726

One of a pair of Windows Notification elevation of privilege flaws fixed together, rated Critical Severity at CVSS 9.8 with 22 percent EPSS on Windows 10 1809 and Server 2019. The notification infrastructure brokers messages across privilege boundaries in every session, which is exactly the pattern behind this month's separate push notification bug cluster. The same cumulative update resolves both pairs.

Do this: Verify this month's rollup is fully deployed on 1809 and Server 2019 rather than tracking these notification bugs individually.
