Description

The Cost Calculator Builder plugin for WordPress is vulnerable to Unauthenticated Payment Status Bypass in all versions up to, and including, 3.6.9 only when used in combination with Cost Calculator Builder PRO. This is due to the complete_payment AJAX action being registered via wp_ajax_nopriv, making it accessible to unauthenticated users, and the complete() function only verifying a nonce without checking user capabilities or order ownership. Since nonces are exposed to all visitors via window.ccb_nonces in the page source, any unauthenticated attacker can mark any order's payment status as "completed" without actual payment.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • stylemix Cost Calculator Builder — Up to and including 3.6.9
  • stylemixthemes cost_calculator_builder — Before 3.6.10
