CVE-2022-36883Network attack vector

Unauthorized builds via unauthenticated webhook parameters

Published Jul 27, 2022 · Updated Aug 3, 2024

Authorization bypass in Jenkins Git Plugin 4.11.3 and earlier allows remote attackers to trigger builds with attacker-chosen Git commits. The /git/notifyCommit webhook accepts unauthenticated GET requests and uses its url and sha1 parameters for repository matching and immediate build scheduling without a permission or token check. An attacker must know a repository URL used by a configured job; a successful request checks out the selected commit and starts that job, altering build inputs and execution.
