No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Cost Calculator Builder plugin for WordPress is vulnerable to unauthorized access of sensitive data due to a missing capability check on the cost-calculator-custom-export-run AJAX action (handler CCBExportImport::export_calculators()) in all versions up to, and including, 3.6.17. The handler only verifies a nonce, but the corresponding ccb_export_nonce is broadcast on every wp-admin page (including pages reachable to Subscribers, such as /wp-admin/profile.php) by the ccb_add_admin_nonces callback hooked to admin_head. This makes it possible for authenticated attackers, with Subscriber-level access and above, to export every calculator's full configuration — including stored Stripe secret keys, PayPal client secrets, Razorpay secret keys, webhook secret keys, and reCAPTCHA secret keys.
