CVE-2025-14757: CWE-862 Missing Authorization in stylemix Cost Calculator Builder
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.
AI Analysis
Technical Summary
CVE-2025-14757 is a missing authorization vulnerability (CWE-862) in the stylemix Cost Calculator Builder WordPress plugin up to version 3.6.9 when combined with Cost Calculator Builder PRO. The vulnerability arises because the complete_payment AJAX action is registered via wp_ajax_nopriv, allowing unauthenticated access. The complete() function only checks a nonce for verification, but since the nonce is exposed to all visitors in the page source, attackers can exploit this to mark orders as completed without payment. This leads to unauthorized payment status changes without proper user capability or order ownership checks.
Potential Impact
An unauthenticated attacker can manipulate the payment status of any order to 'completed' without making a payment, potentially resulting in financial loss or fraudulent transactions. The vulnerability does not affect confidentiality or availability but impacts the integrity of payment processing within the affected plugin versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling the Cost Calculator Builder PRO plugin or restricting access to the complete_payment AJAX action. Monitoring for updates from stylemix and applying any forthcoming patches promptly is recommended.
