 "title": "SureForms – Contact Form Builder, AI Forms, Payment Form, Survey & Quiz <= 2.13.1 - Unauthenticated Payment Bypass via Stripe Subscription Verification",
 "description": "The SureForms plugin for WordPress is vulnerable to Payment Bypass via Stripe subscription and payment verification in versions 2.0.0 up to, and including, 2.13.1. This is due to insufficient verification: the submitted subscription ID was not bound to the payment session, a subscription was accepted in the 'trialing' state without a paid first invoice, and the same completed subscription or PaymentIntent could be submitted again. This makes it possible for unauthenticated attackers to create several paid form entries from a single payment, or entries backed by a subscription whose first payment was not collected.",
