Unauthenticated order completion via unchecked redirect callback
Published Apr 14, 2026 · Updated Apr 14, 2026
Missing authorization in Nexi XPay for WordPress 8.3.0 and earlier allows remote attackers to mark pending WooCommerce orders paid. The redirect path in WC_Gateway_XPay_Process_Completion processes a completion request and changes the referenced order's state without an authorization check. No account or user interaction is required, and the bounded impact is false payment completion for pending orders rather than disclosure or service interruption.
