Unauthenticated order payment spoofing via inverted nonce check
Published Feb 4, 2026 · Updated Feb 4, 2026
Authorization bypass in Fortis for WooCommerce 1.2.0 and earlier allows remote attackers to mark arbitrary orders as paid. The check_fortis_notify_response wc-api callback continues processing when its WordPress nonce check fails, then updates the referenced WooCommerce order. No authentication or user interaction is required; successful requests can set payment state to paid, processing, or completed without payment.
