Unauthenticated Pipeline execution via shared project discovery
Published Jan 24, 2024 · Updated May 30, 2025
Improper project discovery in Jenkins GitLab Branch Source Plugin 684.vea_fa_7c1e2fe3 and earlier allows remote attackers to run crafted Pipelines. GitLabSCMNavigator sends a group-project request without restricting shared results, so an attacker-controlled project shared into the configured owner group is treated as buildable. The attacker must be able to configure and share a GitLab project with that group; Jenkins executes its Pipeline when the next group scan occurs.

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.
