Technical details
This is an Insecure Direct Object Reference (IDOR) vulnerability in the plugin's customer record update functionality. The plugin accepts a mphb_action=update_customer POST request with an arbitrary customer_id parameter and validates only a generic WordPress nonce that is issued to any authenticated user; it does not verify that the authenticated user owns the customer record being modified. An attacker with a low-privileged Subscriber account can enumerate customer IDs and overwrite PII fields (first_name, last_name, email, phone, country). The vulnerability is network-reachable and requires only valid WordPress authentication; no additional user interaction is needed. The fix is available in version 6.2.3 and later, which should add proper ownership verification before permitting customer record modifications.
