Name of the Vulnerable Software and Affected Versions Cost Calculator Builder versions prior to 4.0.2

Description The plugin is susceptible to Unauthenticated Price Manipulation and Insecure Direct Object Reference (IDOR), which occurs when used in combination with Cost Calculator Builder PRO. The issue arises because the 'ccb woocommerce payment' AJAX action is registered via wp ajax nopriv, allowing unauthenticated access. Additionally, the renderWooCommercePayment() function passes user-controlled data to CCBWooCheckout::init() without performing authorization checks. This allows unauthenticated attackers to add WooCommerce products to their cart with prices they control.

Recommendations Update to a version later than 4.0.1. As a temporary workaround, restrict access to the 'ccb woocommerce payment' AJAX action to authenticated users only.
