Authenticated service interruption via crafted API responses

Published Jan 9, 2026 · Updated Jan 9, 2026

Resource exhaustion in GitLab CE/EE allows remote authenticated users to interrupt service through crafted responses from external APIs. The import functionality processes attacker-controlled external API responses without sufficient resource limits; the specific handler and exhausted resource are undisclosed. A GitLab account and import access are required; affected releases are 8.3 through 18.5.4, 18.6 through 18.6.2, and 18.7.0.
