CVE-2024-6678Network attack vector

Arbitrary-user pipeline execution via stop-action identity confusion

Published Sep 12, 2024 · Updated Sep 13, 2024

Authentication bypass in affected GitLab CE/EE releases allows remote authenticated users to trigger pipelines as arbitrary users. The environment stop-action path assigns the stop-action job owner's identity to a pipeline triggered by another user instead of using the triggering user's identity. Low-privilege access is required; affected branches are 8.14 through 17.1.6, 17.2 before 17.2.5, and 17.3 before 17.3.2.
