The Shack Forms Pro extension before 4.0.32 for Joomla! allows path traversal via a file attachment.
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.
