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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=11.1 <17.10.7
- Affected versionversion=17.11 <17.11.3
- Affected versionversion=18.0 <18.0.1
