Summary

The Forminator Forms WordPress plugin before 1.58.4 does not enforce payment on the server side when a form's configured payment gateway is unavailable, allowing unauthenticated visitors to complete a payment-gated User Registration form without paying and be assigned the form's configured role, up to administrator, after the gateway has been connected and later disconnected.
