CVE-2026-32213Network attack vector

Unauthenticated privilege escalation

Published Apr 2, 2026 · Updated Apr 2, 2026

Improper authorization in Microsoft Foundry allows remote attackers to elevate privileges across a network without authentication. Microsoft has not published the affected service component or the authorization check that accepts an unauthorized operation. The network path requires no privileges or user interaction, and successful exploitation crosses a security boundary with full data and service impact.
