Local privilege escalation through missing authentication
Published Aug 11, 2026 · Updated Aug 25, 2026
Missing authentication in Microsoft Windows Remote Desktop Services allows local users to elevate privileges on affected systems. Microsoft identifies a missing authentication check for a critical function but has not disclosed the affected function or operation. Low-privilege local access is required, and successful exploitation grants control over protected data and system operations within the existing security scope.
