Technical details
The vulnerability is classified as an improper enforcement of behavioral workflow (CWE-841) within the pretix-computop payment integration. The root cause is a failure to uniquely bind a payment status response from the Computop gateway to a specific transaction. An attacker can intercept or obtain a successful payment status response and replay it to the system for a different order. This allows for the generation of valid tickets without corresponding payments. The issue is fixed in version 1.3.2 of the pretix-computop plugin.
