CVE-2019-13003Network attack vector

Unauthenticated service interruption via CI parser exhaustion

Published Mar 10, 2020 · Updated Aug 4, 2024

Resource exhaustion in the GitLab CI parser in GitLab Community and Enterprise Edition before 12.0.3 allows remote attackers to interrupt service. GitLab has not published which parser is affected or the specific operation that consumes resources while processing attacker-controlled CI input. Network access without authentication is sufficient, and successful exploitation exhausts resources and interrupts GitLab availability without a reported confidentiality or integrity impact.
