CVE-2022-43421Network attack vector

Unauthorized project triggering via unauthenticated webhook endpoint

Published Oct 19, 2022 · Updated May 8, 2025

Authentication bypass in Jenkins Tuleap Git Branch Source Plugin 3.2.4 and earlier allows remote attackers to trigger Tuleap projects. The /tuleap-hook/ endpoint accepts an attacker-specified repository and dispatches matching configured projects without authenticating the request. Exploitation requires a configured project whose repository matches the supplied value, and the bounded consequence is an unauthorized project trigger.
