The wp-support-plus-responsive-ticket-system plugin before 4.2 for WordPress has directory traversal.
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.
