# CVE-2026-12994: WCFM – Frontend Manager for WooCommerce \<= 6.7.27 - Missing Authorization to Unauthenticated Arbitrary Inquiry Reply Injection via wcfm-my-account-enquiry-manage Controller

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-07-11 · Updated: 2026-07-13

## Affected

- wclovers WCFM – Frontend Manager for WooCommerce: through 6.7.27

## Description

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.
