 "title": "SellKit – Funnel builder and checkout optimizer for WooCommerce to sell more, faster <= 2.7.0 - Unauthenticated Price Manipulation via 'sellkit_product_prices' Parameter",
 "description": "The SellKit plugin for WordPress is vulnerable to Price Manipulation via the 'sellkit_product_prices' parameter in versions 2.3.5 up to, and including, 2.7.0. This is due to the cart price calculation hook (in both the Elementor and block editor checkout implementations) trusting a client-supplied JSON map of product IDs to prices, intended to carry upsell prices back from a hidden checkout form field, and applying those values to matching cart items with set_price() when the order is placed. This makes it possible for unauthenticated attackers to purchase products at arbitrary prices, including zero, by adding the parameter to a checkout submission.",
