Unauthenticated privilege escalation via undisclosed authorization flaw
Published Aug 21, 2025 · Updated Feb 26, 2026
Improper authorization in Microsoft PC Manager allows remote attackers to elevate privileges over a network without authentication. Microsoft has not published the affected component, request path, or authorization check that incorrectly accepts untrusted input. Successful exploitation grants elevated access capable of reading and modifying sensitive data, while the published assessment reports no service-interruption impact.
