The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.7 via the 'wpuf_files_data' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to overwrite the post_title, post_content, and post_excerpt of any arbitrary post on the site, including posts authored by administrators. Exploitation requires access to any WPUF post submission form; this is achievable by users with no WordPress role, as the wpuf_submit_post AJAX action is gated only by a nonce with no capability check for the downstream post-edit operation.
Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
