Advanced Product Fields (Product Addons) for WooCommerce <= 1.6.21 - Unauthenticated Improper Input Validation to Price Bypass via Add-to-Cart POST Request
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.

The Advanced Product Fields (Product Addons) for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.6.17.
