Advisory
Source description from Wordfence Intelligence, credited to Dmitrii Ignatyev.
The Filr – Secure document library plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to 1.2.3.5 (inclusive). This makes it possible for authenticated attackers, with author-level or above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
