An issue was discovered in Joomla! before 3.9.5. The Media Manager component does not properly sanitize the folder parameter, allowing attackers to act outside the media manager root directory.
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.
