CVE-2025-30392Network 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 the Bot Framework SDK. Microsoft has not disclosed the affected SDK method or request path, or the authorization check that incorrectly permits the operation. Network access without authentication is sufficient; the published record establishes privilege elevation but does not identify the resulting privileged actions.
