Events Made Easy permits payment-token binding bypass
Events Made Easy before 3.1.2 does not bind a payment authorization token to the payment record being charged. An unauthenticated attacker can pay a small amount for a low-cost booking, then apply that authorization to a separate higher-priced booking; the plugin accepts the mismatched token and marks the expensive booking fully paid. The payment endpoint, action, token and booking parameters, gateway and validation function are not disclosed. Version 3.1.2 adds price checks for charging and notifications.
