Contao is an Open Source CMS. In affected versions authenticated users in the back end can list files outside the document root in the file selector widget. Users are advised to update to Contao 4.13.49. There are no known workarounds for this vulnerability.
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.
