CVE-2025-47158Network attack vector

Privilege escalation via trusted attacker-controlled data

Published Jul 18, 2025 · Updated Feb 26, 2026

Authentication bypass in Microsoft Azure DevOps allows remote attackers to elevate privileges through network requests. The authentication scheme treats attacker-controllable data as immutable when making an access-control decision. No public advisory identifies the data element or request path, and successful exploitation requires high attack complexity but no prior privileges.
