Description OSIDB Bzimport 2026-09-02 15:58:29 UTC 
In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, objects of types marked as storing their configuration in independent top-level configuration files in Jenkins (such as the global configuration and jobs) can appear as nested field values in user-submitted `config.xml` documents and subsequently handle HTTP requests via Stapler, resulting in remote code execution.
