WatchTowerHQ <= 3.16.0 - Authenticated (Administrator+) Arbitrary File Read via 'wht_download_big_object_origin' Parameter
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The WatchTowerHQ plugin for WordPress is vulnerable to arbitrary file read via the 'wht_download_big_object_origin' parameter in all versions up to, and including, 3.16.0. This is due to insufficient path validation in the handle_big_object_download_request function. This makes it possible for authenticated attackers, with administrator-level access and a valid access token, to read arbitrary files on the server, which can contain sensitive information such as database credentials and authentication keys.
