 "title": "Forminator Forms <= 1.57.3.1 - Unauthenticated PayPal Order Request Tampering via Form Submission",
 "description": "The Forminator Forms plugin for WordPress is vulnerable to request tampering in its PayPal order creation handler in all versions up to, and including, 1.57.3.1 due to client-supplied request data being merged into the PayPal create-order request. This makes it possible for unauthenticated attackers to add their own properties to the order sent to PayPal, such as an additional purchase unit, a payee or an application context, on forms that use a PayPal field. The amount recorded for the submission is re-validated against the form settings before the payment is captured.",
