Technical details

The plugin fails to validate the client-supplied "payment_portion" parameter against server-side configured amounts for the service and site, allowing an unauthenticated attacker to set the amount due to zero. By sending a malicious request during booking, an attacker can obtain a confirmed appointment and recorded order without completing payment, bypassing all payment validation logic.
