User Frontend <= 4.3.11 - Authenticated (Subscriber+) Subscription-Gated Post Creation
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.
