Advisory
Source description from Wordfence Intelligence, credited to Krzysztof Zając.
The rtMedia for WordPress, BuddyPress and bbPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the rtmedia_api_process_rtmedia_upload_media_request() function in all versions up to, and including, 4.6.15. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
