Authenticated remote code execution
Published Jan 16, 2026 · Updated Jan 16, 2026
Improper authorization in Microsoft Power Apps Desktop Client before 25121 allows remote authenticated users to execute code over a network. Microsoft has not disclosed which authorization check the client omits or what user-controlled request reaches the code-execution path. Exploitation requires low-privileged access and user interaction, and successful exploitation runs attacker-chosen code in the client's security context.
