The Snap Creek Duplicator plugin before 1.3.28 for WordPress (and Duplicator Pro before 3.8.7.1) allows Directory Traversal via ../ in the file parameter to duplicator_download or duplicator_init.
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.
