The Pinpoint Booking System – Version 2 plugin for WordPress is vulnerable to Price Manipulation via the cart_data parameter in all versions up to, and including, 2.9.9.6.8. This is due to the dopbsp_woocommerce_add_to_cart AJAX action being registered via wp_ajax_nopriv_* with no authentication, no nonce verification, and no server-side recalculation of pricing — the update handler reads price_total directly from the attacker-controlled cart_data POST parameter and persists it to the database via $wpdb->insert() without validating it against the calendar's configured pricing. The woocommerce_before_calculate_totals callback subsequently reads the stored attacker-supplied value back from the database and passes it directly to $product->set_price() without recomputing from calendar settings. This makes it possible for unauthenticated attackers to override the WooCommerce checkout price of any bookable product tied to a booking calendar to an arbitrary value, effectively enabling the purchase of any such product at a self-chosen price.
