CVE-2026-2996

Published on
Aug 22, 2026
Research Description
The Advanced Product Fields (Product Addons) for WooCommerce plugin for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 1.6.21. This is due to a logic flaw in the 'validate_cart_data' function. This makes it possible for unauthenticated attackers to bypass required paid addons and complete purchases at the base product price only, effectively stealing products by paying a fraction of the intended total. The vulnerability was partially patched in version 1.6.19.
Affected versions
max 1.6.22.
Status
vulnerable
