CVE-2026-8692
Vedrixa Forms <= 1.1.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Form Structure Modification via wefb_save_form_structure AJAX Action
The Vedrixa Forms – User Registration Form, Signup Form & Drag & Drop Form Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the structure of any form — adding, removing, or altering fields — by writing attacker-controlled data to the plugin's FORMS database table. The 'ajax-nonce' nonce used by this handler is injected into the public frontend via wp_localize_script(), so any authenticated user who visits a page containing a form shortcode can obtain it without any elevated access.
