CVE-2026-35435 is a critical elevation-of-privilege vulnerability in Azure AI Foundry M365 published agents caused by improper access control. The flaw affected authorization enforcement in agent-related operations for the hosted service used to publish AI agents into Microsoft Teams and Microsoft 365 Copilot. An unauthorized attacker could exploit the issue remotely over the network without prior authentication or user interaction. Microsoft assessed the vulnerability with changed scope and high confidentiality impact, indicating that exploitation could cross a security boundary and expose data beyond the vulnerable component itself. The service is an exclusively hosted cloud offering, and Microsoft did not disclose further technical details about the exploit path or specific vulnerable routines.
