Summary

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.

Risk Assessment

Risk of financial loss and product theft, as attackers can purchase products without paying for required addons.

Recommendation

Update the Advanced Product Fields plugin to the latest version that includes the full fix. Check for unauthorized orders.
