Summary
rtMedia for WordPress, BuddyPress and bbPress is affected up to and including 4.7.13. The process function lacks an authorization check (CWE-862) and validates file paths insufficiently. An unauthenticated remote attacker can delete arbitrary safe files on the server, because the required nonce is exposed to visitors in frontend JavaScript.

Description from the CNA
The rtMedia for WordPress, BuddyPress and bbPress plugin for WordPress is vulnerable to limited file deletion due to insufficient file path validation in the process function in all versions up to, and including, 4.7.13 This makes it possible for unauthenticated attackers to delete arbitrary safe files on the server.. The public nonce (rtmedia_upload_nonce) is emitted into frontend JavaScript on any page rendering the rtMedia gallery or upload shortcode, making it retrievable by unauthenticated visitors without any prior authentication or privileged action.
