CVE-2024-0619Network attack vector

Unauthenticated order-status modification via unchecked callback

Published Jul 11, 2024 · Updated Apr 8, 2026

Missing authorization in Payflex Payment Gateway 2.5.0 and earlier allows remote attackers to alter WooCommerce order statuses. The payment_callback() handler trusted callback-supplied status data instead of confirming the order status through Payflex's remote API. An internet-reachable store with the gateway enabled exposes the callback, allowing forged data to alter an order's recorded payment state and cause revenue loss.
