CVE-2024-8973Network attack vector

Authenticated service interruption via crafted GitHub imports

Published May 9, 2025 · Updated May 9, 2025

Denial of service in GitLab CE/EE allows remote authenticated users to interrupt service with crafted GitHub import requests. GitLab has not publicly disclosed which GitHub import API handler accepts the payload or how processing it consumes resources without an effective limit. An authenticated account with access to GitHub project import is required, and the documented consequence is service unavailability rather than data disclosure or modification.
