Microsoft 365 Copilot For Android
Monthly
Remote code execution in the Microsoft 365 Copilot mobile apps for Android and iOS lets an unauthenticated attacker run code across a security boundary by getting a user to interact with crafted content (CWE-77 command injection). The CVSS 9.6 rating reflects network reach, low complexity, no privileges, and a changed scope with high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis, but a vendor patch is available and the flaw was self-reported by Microsoft.
Improper access control in M365 Copilot allows an authorized attacker to perform spoofing locally.
CVE-2026-26133 is an AI command injection vulnerability in Microsoft 365 Copilot and multiple Microsoft mobile/desktop applications that allows remote attackers to disclose sensitive information through crafted AI prompts. The vulnerability affects numerous Microsoft products across iOS, Android, and macOS platforms, requires user interaction, and has a patch available from Microsoft with no current evidence of active exploitation (not in KEV).
