No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Wallet for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.6.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to enumerate the login name, email address, and user ID of all WordPress accounts — including administrators — by submitting arbitrary search terms to the AJAX handler. The required 'search-user' nonce is localized into the wallet_param object on the standard WooCommerce My Account page, which is accessible to any authenticated user, making it trivially obtainable by a Subscriber.
