The WCFM – Frontend Manager for WooCommerce plugin for WordPress (up to version 6.7.25) has an Insecure Direct Object Reference (IDOR) vulnerability in multiple AJAX actions. Missing validation on user-supplied object IDs allows authenticated attackers with Vendor-level access or higher to modify any order, delete or modify any post/product/page regardless of ownership.
Original NVD description (English source)
The WCFM – Frontend Manager for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.7.27. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to inject arbitrary reply content into any store inquiry, overwrite the main inquiry record in wp_wcfm_enquiries, and trigger unsolicited notification emails to customers and vendors. Unlike sibling controller branches (wcfm-enquiry and wcfm-enquiry-manage), the wcfm-my-account-enquiry-manage branch performs no is_user_logged_in() or current_user_can() check, and the nonce that serves as the sole barrier is embedded into every public page load without any login gate.
