CVE-2019-5462Public exploitNetwork attack vector

Pipeline impersonation via unrotated trigger tokens

Published Jan 28, 2020 · Updated Aug 4, 2024

Privilege escalation in GitLab CE/EE 9.0 and later allows remote authenticated users to run pipelines as a new token owner. Changing ownership reassigns the trigger token without rotating its secret, and the pipeline API continues accepting the value known by the former owner. Exploitation requires prior knowledge of that token and permits pipeline execution under the new owner's identity.
