GitLab has remediated an issue in GitLab CE/EE affecting all versions from 13.0 before 18.8.9, 18.9 before 18.9.5, and 18.10 before 18.10.3 that could have allowed an unauthenticated user to cause denial of service by sending repeated GraphQL queries.
AnalysisAI
Denial of service in GitLab CE/EE versions 13.0 through 18.10.2 allows unauthenticated remote attackers to exhaust server resources via repeated GraphQL queries. Affects all installations from version 13.0 before patched releases 18.8.9, 18.9.5, and 18.10.3. Attackers can degrade or halt GitLab service availability without authentication, impacting development workflows and CI/CD pipelines. No public exploit identified at time of analysis.
Technical ContextAI
CWE-1284 (Improper Validation of Specified Quantity in Input) indicates GraphQL endpoint lacks proper rate limiting or query complexity controls. Repeated queries overwhelm server resources through uncontrolled request processing. Vulnerability persisted across major versions since GitLab 13.0, suggesting architectural resource management deficiency in GraphQL parser or execution layer.
RemediationAI
Vendor-released patch: upgrade immediately to GitLab 18.8.9, 18.9.5, or 18.10.3 depending on your major version track. If immediate patching is impossible, implement network-level rate limiting on GraphQL endpoints (/api/graphql) or temporarily restrict GraphQL access to authenticated sessions only via reverse proxy rules. Monitor resource utilization and implement query complexity limits if custom deployments allow.
