User Frontend
Monthly
Unauthenticated content tampering in the WP User Frontend WordPress plugin (all versions through 4.3.7) allows any visitor to overwrite the title, body, and excerpt of any post on the site, including posts authored by administrators. The flaw stems from the wpuf_submit_post AJAX action accepting a user-controlled post reference key in the wpuf_files_data parameter without validating whether the requesting user is authorized to edit the target post - a textbook CWE-639 authorization-through-user-controlled-key failure. No public exploit code or active exploitation has been identified at time of analysis, but the attack requires no authentication and no special configuration beyond the plugin being installed with at least one public-facing submission form.
Authorization bypass in the WP User Frontend (WPUF) WordPress plugin through version 4.3.7 allows unauthenticated visitors to delete guest-uploaded media attachments via the wpuf_file_del AJAX action. The plugin's sole access control gate - a WordPress nonce - is self-defeated: when any WPUF shortcode is rendered on a public front-end page, the nonce value is localized into publicly readable JavaScript objects (wpuf_upload and wpuf_frontend), making it trivially extractable by any browser visitor. No active exploitation has been confirmed (not in CISA KEV), and no public exploit code has been identified, but the zero-authentication, low-complexity attack path makes this trivially reproducible from plugin source code alone.
Insecure Direct Object Reference in weDevs WP User Frontend plugin (all versions ≤4.3.1) allows unauthenticated network attackers to activate a free subscription tier on behalf of any registered WordPress user by supplying an arbitrary user_id to the payment_page() function, silently overwriting existing paid subscriptions and revoking premium access. The root cause is a missing authorization check on a user-controlled key (CWE-639), and because WordPress user IDs are sequential integers trivially enumerable via the REST API, this is exploitable at scale with no authentication or user interaction. No public exploit has been identified at time of analysis, but the zero-privilege, low-complexity attack path makes this straightforward to weaponize against any site monetizing through this plugin's membership features.
