CVE-2025-14755
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Cost Calculator Builder plugin for WordPress is vulnerable to Unauthenticated Price Manipulation and Insecure Direct Object Reference (IDOR) in all versions up to, and including, 4.0.1 only when used in combination with Cost Calculator Builder PRO. This is due to the ccb_woocommerce_payment AJAX action being registered via wp_ajax_nopriv, making it accessible to unauthenticated users, and the renderWooCommercePayment() function passing user-controlled data directly to CCBWooCheckout::init() without authorization checks. This makes it possible for unauthenticated attackers to add WooCommerce products to their cart with attacker-controlled prices.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Cost Calculator Builder WordPress plugin registers an AJAX action (ccb_woocommerce_payment) via wp_ajax_nopriv, making it accessible to unauthenticated users. The renderWooCommercePayment() function passes user-supplied price data directly to CCBWooCheckout::init() without any server-side validation or authorization checks, allowing attackers to add WooCommerce products to their cart with arbitrary prices.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Cost Calculator Builder plugin is installedGo to WordPress Admin > Plugins and confirm 'Cost Calculator Builder' is installed and note the installed version numberAffected if Plugin is installed and version is below 4.0.2 or version cannot be determined
-
Confirm WooCommerce is installed and activeGo to WordPress Admin > Plugins and check if WooCommerce is installed and activatedAffected if WooCommerce is active, as the vulnerability exploits the WooCommerce integration
-
Check if WooCommerce integration is enabled in Cost Calculator Builder settingsNavigate to Cost Calculator Builder settings in WordPress admin and look for WooCommerce integration settings. Check if the integration toggle or option is enabledAffected if WooCommerce integration is enabled in the plugin settings
-
Test unauthenticated access to the vulnerable AJAX endpointSend a POST request to /wp-admin/admin-ajax.php with action=ccb_woocommerce_payment and verify the endpoint responds without authentication (check HTTP status 200)Affected if The endpoint returns a valid response without requiring authentication (status 200 instead of 401/403)

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Cost Calculator Builder to version 4.0.2 or later. Until then, disable the WooCommerce integration or add custom code to block unauthenticated access to the affected AJAX endpoint and implement server-side price validation.
