CVE-2026-82211Network attack vectorHinoki check available

Unauthenticated order manipulation via unchecked payment results

Published Oct 7, 2026 · Updated Oct 7, 2026

Payment-result validation failure in Nexi XPay Build 7.0.0 through 7.6.2 allows remote attackers to alter WooCommerce orders. Several unauthenticated payment-result routes accept a supplied outcome without verifying it before updating an order or returning its key. On a reachable merchant site, forged results can mark arbitrary orders paid or failed or cancel them, while disclosed order keys expose guest buyers' details.
