Jenkins HTML Publisher Plugin 1.32 and earlier archives invalid symbolic links in report directories on agents and recreates them on the controller, allowing attackers with Item/Configure permission to determine whether a path on the Jenkins controller file system exists, without being able to access it.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
