Status: published. Published: 2026-11-11. Updated: 2026-11-11.

The Advanced Product Fields (Product Addons) for WooCommerce WordPress plugin from 1.6.22 to 1.7.3 does not validate that a submitted value for a required paid product option matches one of the configured choices, only that it is not empty, allowing unauthenticated users to add a product to the cart and complete an order while skipping the required option's surcharge and paying only the base product price.
