WPForms Lite 1.8.8.2 - 2.0.1.1 - Unauthenticated Stripe Refund and Subscription Cancellation via External PaymentIntent

The WPForms WordPress plugin before 2.0.2 does not verify that a Stripe payment object supplied during a public form submission belongs to it before acting on it, allowing unauthenticated users to trigger a full refund and an immediate subscription cancellation against payments created by other applications on the site owner's Stripe account.
