Advisory
Source description from Wordfence Intelligence, credited to Supakiad S. (m3ez).
The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the user_subscription_cancel() function in all versions up to, and including, 4.3.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to cancel any user's subscription pack, including administrators.
