Authorization bypass via GraphQL mutations through GitLab GLQL API endpoint

IdentifiersCVE-2025-14592CWE-285

GitLab CE/EE contains an authorization issue affecting versions 18.6 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4 where, under certain conditions, an authenticated user could perform unauthorized operations by submitting GraphQL mutations through the GLQL API endpoint. This is effectively an authorization bypass in the GLQL/GraphQL mutation handling path that allows actions beyond the attacker’s intended permissions.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An authenticated attacker may be able to perform unauthorized operations (authorization bypass) by sending GraphQL mutations via the GLQL API endpoint under certain conditions.

Mitigation

If you can’t patch tonight, do this now.

Restrict or disable access to the GLQL API endpoint until patching is complete. Apply network/reverse-proxy/WAF controls to limit which authenticated users can reach the GLQL endpoint, enforce least-privilege access, and monitor for suspicious GraphQL mutation activity targeting the GLQL endpoint.

Remediation

Patch, then assume compromise.

Upgrade GitLab CE/EE to a fixed release: 18.6.6 or later (within 18.6), 18.7.4 or later (within 18.7), or 18.8.4 or later (within 18.8).
