Unauthenticated security feature bypass
Published Oct 13, 2026 · Updated Oct 13, 2026
Cryptographic weakness in Microsoft Windows Remote Desktop allows remote attackers to bypass a security feature over a network. The published record does not identify the cryptographic algorithm, the affected code path, or the security feature that fails. Exploitation requires user interaction, but the required action and the concrete consequences of the bypass are undisclosed.
