Jenkins FilePath.untarFrom() does not validate symlink targets when extracting TAR archives, allowing an attacker with Item/Configure permission to create symlinks from a workspace to arbitrary files on the Jenkins controller. This issue remains exploitable in versions patched for CVE-2026-33001 and CVE-2026-70427. An attacker can use this to read sensitive files from $JENKINS_HOME, including Jenkins cryptographic keys and stored credentials.
