Security patch for django-filer

The updated release 2.2.5 is now available from our GitHub repository and PyPI.

Details

django filer did not check permissions properly for listing directories, moving files or folders, or uploading files. Effectively, a staff user without any permissions could thereby browse filer's folder tree if they knew the url. This vulnerability would expose the folder tree and the files to a staff user without permissions.

Please see the relevant commits on GitHub for more information about the vulnerability and mitigation.
