Technical details
The vulnerability is an Insecure Direct Object Reference (IDOR) in the order bump checkout mechanism. The plugin accepts a product ID parameter in the wpfnl_order_bump_ajax AJAX action without validating that the requested product matches the discount configuration for that specific order bump. An unauthenticated attacker can supply a different product_id or variation_id while retaining the discount percentage intended for a cheaper item, causing WooCommerce to apply the reduced price to any substituted product. The attack requires only a valid WooCommerce session nonce (publicly available in page markup) and works against any checkout with order bumps enabled. Patches are available in version 3.13.0 and later.
