Local privilege escalation via missing authentication
Published Aug 11, 2026 · Updated Aug 25, 2026
Authentication bypass in Windows Remote Desktop Services in Microsoft Windows allows local users to gain higher privileges. Microsoft describes the flaw only as missing authentication for a critical RDS function and has not published the specific code path or operation that accepts insufficiently authenticated local requests. Exploitation requires local authenticated access, and the public record supports host-level privilege escalation rather than a network-reachable Remote Desktop server compromise.
