Pipeline authorization bypass via mismatched pipeline identifiers
Published May 23, 2024 · Updated Aug 29, 2024
Authorization bypass in GitLab allows remote authenticated users to bypass required pipeline success checks through the commits API. The Set Pipeline Status of a Commit API accepts a commit SHA paired with an unrelated pipeline_id and creates a successful external pipeline instead of rejecting the mismatch. An API token and a merge request requiring a successful pipeline let the crafted status become the latest pipeline, permitting a merge despite a failing real pipeline.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=16.10 <16.10.6
- Affected versionversion=16.11 <16.11.3
