Description
The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 9.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the saved_admin_email, saved_user_email, and saved_user_email_address fields of arbitrary form entries belonging to other users, and cause the site to dispatch attacker-controlled email content to attacker-chosen recipient addresses.
