## Description

An incomplete patch for CVE-2026-33001 in Jenkins Project Jenkins through LTS 2.555.3 allows an authenticated remote attacker with Item/Configure permission to read arbitrary files on the Jenkins controller filesystem via a crafted tar archive. The CVE-2026-33001 security update validates symlink destinations during tar extraction in FilePath.java but does not validate symlink targets; a symlink whose location is inside the workspace can still point to arbitrary paths outside it, enabling disclosure of any file readable by the Jenkins process user, including secrets/master.key, credentials.xml, and other sensitive configuration files.

## Affected Products
