CVE-2023-46655

Name of the Vulnerable Software and Affected Versions Jenkins CloudBees CD Plugin versions 1.1.32 and earlier

Description The issue allows attackers who can configure jobs to publish arbitrary files from the Jenkins controller file system to the previously configured CloudBees CD server. This is due to the plugin following symbolic links to locations outside of the directory from which artifacts are published during the 'CloudBees CD - Publish Artifact' post-build step. The plugin temporarily copies files from an agent workspace to the controller in preparation for publishing them, and in versions 1.1.32 and earlier, it follows symbolic links to locations outside of the temporary directory on the controller when collecting the list of files to publish.

Recommendations For Jenkins CloudBees CD Plugin versions 1.1.32 and earlier, update to version 1.1.33 or later to ensure that only files located within the expected directory are published. As a temporary workaround, consider restricting access to the 'CloudBees CD - Publish Artifact' post-build step to minimize the risk of exploitation.
