CVE-2025-30389Network attack vector

Unauthenticated privilege elevation via undisclosed authorization flaw

Published Apr 30, 2025 · Updated Aug 10, 2026

Improper authorization in Microsoft Azure AI Bot Service allows remote attackers to elevate privileges through Bot Framework SDK requests. Microsoft has not published the affected component or the incorrect authorization operation performed on an untrusted request. Exploitation requires unspecified high-complexity conditions but no authentication or user interaction, and it can expose or alter service data without interrupting availability.
