Technical details
The pretix-oppwa plugin (the Oppwa-based payment integration for pretix) contains a logic flaw in its payment status validation. The component fails to sufficiently verify that a payment status response corresponds to the specific transaction being processed. An attacker can exploit this by capturing a successful payment status response from one transaction and replaying or supplying it to the system for a different order. This results in the system marking multiple orders as paid based on a single actual payment. The vulnerability is fixed in version 1.4.3.
