Technical details
RegistrationMagic fails to validate the total price of paid registrations on the server side, relying instead on client-side price parameters that an attacker can freely manipulate. The vulnerability affects the plugin's payment processing logic when handling Price fields in registration forms. An unauthenticated attacker can submit a registration request with the quantity set to 0 or the price field omitted entirely, causing the plugin to record the transaction as "Completed" for $0.00 while still activating the user account. No payment gateway communication occurs in these cases. The vulnerability was fixed in version 6.0.9.9; versions up to 6.0.9.8 are affected.
