CVE-2025-11974Network attack vector

Service interruption via oversized API uploads

Published Oct 27, 2025 · Updated Oct 28, 2025

Resource exhaustion in GitLab CE/EE allows remote attackers to interrupt service by uploading large files to specific API endpoints. GitLab has not disclosed the affected endpoints or the server-side operation that accepts uploads without an effective resource limit. The advisory describes unauthenticated reachability, while its CVSS vector requires low privileges; the bounded impact is service interruption.
