CVE-2026-13222 · Severity: info · CVSS 6.3 · Published 2026-06-25

A vulnerability in the Oppwa payment integration for the pretix ticketing system allows users to bypass payment requirements. By reusing a valid payment confirmation from one transaction for a different order, an attacker can obtain multiple tickets while only paying for one. This could lead to financial loss for event organizers and unauthorized access to events.

## 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.
