Jenkins Warnings Next Generation Plugin 9.10.2 and earlier does not restrict the name of a file when configuring custom ID, allowing attackers with Item/Configure permission to write and read specific files with a hard-coded suffix on 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.
