CVE-2026-57536Network attack vector

Multiple-ticket issuance via cross-payment status replay

Published Jun 25, 2026 · Updated Jun 25, 2026

Improper workflow validation in pretix-mollie before 2.5.6 allows remote attackers to obtain multiple tickets with one payment. The payment-status handler accepts a successful Mollie response without binding it to the payment record being completed. Exploitation requires one successful payment and replaying its status for other payment records; it alters ticket entitlement without exposing data.
