CVE-2019-20146Network attack vector

Remote service interruption

Published Jan 13, 2020 · Updated Aug 5, 2024

Uncontrolled resource consumption in GitLab CE and EE 11.0 through 12.6 allows remote attackers to degrade service availability. The published records do not disclose the specific endpoint, parser, or resource-management operation that consumes resources. Unauthenticated network access is sufficient according to the CVSS assessments, with impact limited to service availability degradation and no reported confidentiality or integrity effect.
