Description
The Forminator Forms plugin for WordPress is vulnerable to Sensitive Information Exposure via the Stripe Checkout pending-entry response in all versions up to, and including, 1.58.3. This is due to the plugin returning the form's after-payment behavior (thank-you message or redirect URL) for a pending entry based only on the payment-owner browser token, without confirming that the Stripe Checkout Session was completed. This makes it possible for unauthenticated attackers to start a checkout and then receive the post-payment message or redirect URL, which may give access to content gated behind payment, without paying.
