WordPress Plugin Vulnerabilities

Advanced Product Fields (Product Addons) for WooCommerce 1.6.22 - 1.7.3 - Unauthenticated Paid Option Surcharge Bypass via Add-to-Cart Choice Field

Description

The plugin 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.
