- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial

- Published: 2026-02-04 · Updated: 2026-04-08

## Affected

- fortispay Fortis for WooCommerce: through 1.2.0

## 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.
