The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.
