CVE-2025-21385Network attack vector

Authenticated information disclosure via server-side request forgery

Published Jan 9, 2025 · Updated Jun 9, 2026

Server-side request forgery in Microsoft Purview allows remote authenticated users to disclose information through server-originated network requests. Microsoft has not published the affected component or the input-handling operation that permits attacker-controlled request destinations. Low-privileged access is required, no user interaction is needed, and the disclosed consequence is information exposure over a network.
