Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Jenkins ByteGuard Build Actions Plugin, versions 1.0 and earlier, stores API tokens unencrypted in job config.xml files on the Jenkins controller and does not mask them on the job configuration form. An attacker with Item/Extended Read permission or access to the controller file system can view these tokens. No fix is listed as of publication.
