Technical details

A command injection vulnerability (CWE-77) exists in Microsoft 365 Copilot for Android and iOS due to improper neutralization of special elements used in a command. The vulnerability can be exploited over the network by an unauthenticated attacker, though it requires some level of user interaction (UI:R). Successful exploitation allows for remote code execution with a 'Changed' scope (S:C), meaning the attacker can impact resources beyond the Copilot application itself. Microsoft has addressed this issue in the July 2026 security updates.
