An issue was discovered in Squiz Matrix from 5.3 through to 5.3.6.1 and 5.4.1.3. An information disclosure caused by a Path Traversal issue in the 'File Bridge' plugin allowed the existence of files outside of the bridged path to be confirmed.
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.
