CSRF in GitLab GraphQL API
CVE-2026-4922 is a cross-site request forgery vulnerability in GitLab CE/EE affecting the GraphQL API, specifically the /api/graphql endpoint. According to the provided content, affected versions are all releases from 17.0 before 18.9.6, 18.10 before 18.10.4, and 18.11 before 18.11.1. The issue is caused by insufficient CSRF protection on GraphQL mutation requests: the endpoint accepted state-changing mutation operations using a victim’s valid session cookies without properly enforcing anti-forgery validation or origin checks. As a result, an unauthenticated attacker could induce an authenticated GitLab user to load a malicious page and thereby cause GraphQL mutations to execute under that user’s identity.
