WPForms – AI Form Builder for WordPress – Contact Forms, Payment Forms, Survey Form, Quiz & More 1.10.0.1 - 2.0.2.1 - Unauthenticated Payment Bypass on Paid Forms
The WPForms – AI Form Builder for WordPress – Contact Forms, Payment Forms, Survey Form, Quiz & More plugin for WordPress is vulnerable to Payment Bypass in versions 1.10.0.1 through 2.0.2.1. This is due to missing server-side enforcement that blocks submission when no PayPal payment identifier is present, and a conditional check that allowed form errors to be suppressed when the PayPal Commerce field was not marked required in the form builder. This makes it possible for unauthenticated attackers to submit a PayPal Commerce payment form without completing payment, receiving the form confirmation and notification emails without any order existing at PayPal. A form must have a PayPal Commerce payment field.
