CVE-2025-3279Network attack vector

Authenticated service interruption via crafted GraphQL requests

Published Jun 26, 2025 · Updated Jun 26, 2025

Resource exhaustion in affected GitLab CE/EE releases allows remote authenticated users to interrupt service via crafted GraphQL requests. GitLab has not published which GraphQL resolver or resource-allocation operation fails to limit attacker-controlled work. A valid account is required; successful requests consume enough server resources to make the GitLab service unavailable, without reported data exposure or modification.
