Advisory
Source description from Wordfence Intelligence, credited to Erwan LR.
The User Frontend plugin for WordPress is vulnerable to Payment Bypass in all versions up to, and including, 4.3.11. This is due to missing server-side validation of submission state, allowing a client-supplied `wpuf_form_status` field (or the absence of `post_id`) to bypass the subscription-pack gate in the post-creation handler. This makes it possible for authenticated attackers, with subscriber-level access and above, to create and publish posts through subscription-gated forms without purchasing the required subscription pack.
