CVE-2026-57536: pretix pretix-mollie improper payment status validation

CVE-2026-57536 · Severity: info · CVSS 6.3 · Published 2026-06-25

The pretix-mollie plugin, used for processing payments in the pretix ticketing system, failed to properly verify payment confirmation messages.

Technical details

The vulnerability is classified as CWE-841 (Improper Enforcement of Behavioral Workflow) within the pretix-mollie plugin. The root cause is insufficient validation of payment status responses from the Mollie payment gateway. An attacker can capture a valid 'success' response from one transaction and replay or supply it to the system for a different, unpaid transaction. This allows the attacker to bypass the payment requirement for subsequent tickets. The vulnerability is fixed in pretix-mollie version 2.5.6.
