CVE-2026-4922 is a cross-site request forgery vulnerability in GitLab CE/EE affecting the GraphQL API, specifically state-changing mutation operations exposed through the GraphQL endpoint. The flaw stems from insufficient CSRF protection and inadequate validation of the origin of mutation requests, allowing the endpoint to accept requests authenticated only by the victim’s existing session cookies without enforcing proper anti-forgery checks. As a result, an unauthenticated attacker can induce a logged-in GitLab user to submit forged GraphQL mutation requests that execute under that user’s identity. Affected versions are all GitLab CE/EE releases from 17.0 before 18.9.6, 18.10 before 18.10.4, and 18.11 before 18.11.1.
