CVE-2023-46655: Improper Link Resolution Before File Access ('Link Following')

October 25, 2023 (updated November 1, 2023)

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.
