Jenkins CloudBees CD Plugin 1.1.32 and earlier follows symbolic links to locations outside of the directory from which artifacts are published during the 'CloudBees CD - Publish Artifact' post-build step, allowing attackers able to configure jobs to publish arbitrary files from the Jenkins controller file system to the previously configured CloudBees CD server.

In Jenkins CloudBees CD Plugin, artifacts that were previously copied from an agent to the controller are deleted after publishing by the 'CloudBees CD - Publish Artifact' post-build step.

CloudBees CD Plugin 1.1.32 and earlier follows symbolic links to locations outside of the expected directory during this cleanup process.

This allows attackers able to configure jobs to delete arbitrary files on the Jenkins controller file system.

CloudBees CD Plugin 1.1.33 deletes symbolic links without following them.
