CVE-2024-12093Network attack vector

Authenticated 2FA bypass via modified SAML response

Published May 22, 2025 · Updated May 22, 2025

Improper XPath validation in affected GitLab CE/EE releases allows remote authenticated users to bypass required 2FA via modified SAML responses. GitLab has not disclosed the XPath expression, validation routine, or exact inconsistency that causes a modified response to be accepted. Exploitation requires low-privileged access, high-complexity specialized conditions, and SAML authentication; success exposes data and actions protected by the 2FA gate.
