CVE-2025-10867Network attack vector

Authenticated service interruption via unthrottled blobSearch requests

Published Sep 26, 2025 · Updated Sep 26, 2025

Resource exhaustion in GitLab CE/EE allows remote authenticated users to interrupt service through repeated GraphQL blobSearch requests. The blobSearch field in the unprotected GraphQL API accepts repeated queries without resource limits or throttling, allowing request-driven work to accumulate. Successful exploitation requires a valid account and user interaction; the published impact is limited to reduced availability, not data disclosure or modification.
