Jenkins Pipeline Utility Steps Plugin 2.13.1 and earlier does not restrict the set of enabled prefix interpolators and bundles versions of Apache Commons Configuration library that enable the 'file:' prefix interpolator by default, allowing attackers able to configure Pipelines to read arbitrary files from the Jenkins controller file system.
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.
