Technical details
The vulnerability is a payment status response validation bypass in Pretix's Adyen payment integration. An attacker can supply a legitimate payment status response from one completed payment to the system as if it applies to a different payment, allowing them to claim fulfillment (ticket issuance) without payment. This requires network access to the payment callback mechanism but no authentication or special preconditions beyond initiating a purchase.
