Fortis for WooCommerce <= 1.2.0 - Missing Authorization to Unauthenticated Arbitrary Order Status Update to Paid via 'wc-api' Endpoint

Missing Authorization
CVE CVE-2026-0679
CVSS Medium (5.3)
Publicly Published February 3, 2026
Last Updated February 16, 2026
Researcher Md. Moniruzzaman Prodhan (NomanProdhan)
Description

The Fortis for WooCommerce plugin for WordPress is vulnerable to authorization bypass due to an inverted nonce check in the 'check_fortis_notify_response' function in all versions up to, and including, 1.2.0. This makes it possible for unauthenticated attackers to update arbitrary WooCommerce order statuses to paid/processing/completed, effectively allowing them to mark orders as paid without payment.
