Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins Filesystem List Parameter Plugin versions before 0.0.15 do not restrict the path used by its File system objects list parameter. An attacker with Item/Configure permission can enumerate file names on the Jenkins controller file system. Upgrade to version 0.0.15 or later, which limits these paths to an allow list whose default base directory is $JENKINS_HOME/userContent/ and which can be configured to include other base directories.
