Lifecycle Timeline

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.
AnalysisAI
User enumeration via authorization bypass in the Wallet for WooCommerce WordPress plugin (versions up to and including 1.6.4) allows any authenticated subscriber-level user to extract login names, email addresses, and user IDs for every WordPress account on the site, including administrators. The flaw exists because the plugin exposes a 'search-user' nonce - required to call its AJAX search handler - directly in the wallet_param JavaScript object rendered on the publicly accessible WooCommerce My Account page, making it trivially obtainable by any logged-in user. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the low attack complexity and wide subscriber-level accessibility make exploitation straightforward on sites with open user registration.
Technical ContextAI
The affected component is the Wallet for WooCommerce WordPress plugin by vendor subratamal (CPE: cpe:2.3:a:subratamal:wallet_for_woocommerce:*:*:*:*:*:*:*:*), a digital wallet extension for WooCommerce. The root cause is CWE-862 (Missing Authorization): the AJAX handler does not verify that the requesting user holds sufficient privileges to search the full user database. The plugin registers an AJAX action backed by class-woo-wallet-ajax.php (lines 56 and 166), which calls a user-search utility in woo-wallet-util.php (line 1462) without performing a capability check. Critically, class-woo-wallet-frontend.php (line 199) localizes the 'search-user' nonce into the wallet_param JavaScript object on every page load of the WooCommerce My Account page - a page accessible to all authenticated users. This design eliminates any practical nonce secrecy, reducing the authorization gate to a formality bypassable by any authenticated session. The upstream fix is reflected in WordPress plugin trac changeset 3585829.
RemediationAI
Update the Wallet for WooCommerce plugin to the first version released after changeset 3585829 on the WordPress plugin repository; the exact patched version number is not independently confirmed in the available advisory data, so administrators should verify the current version in the WordPress plugin directory against the changelog. The Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/98b38844-c6fe-4655-8bbe-7600203b567e should be monitored for a confirmed fixed version designation. As an immediate compensating control on sites that cannot patch promptly, disable open user registration (Settings > General > 'Anyone can register') to eliminate unauthenticated users from obtaining the subscriber session required to exploit this flaw - this closes the primary attack path but will also prevent legitimate new user self-registration. Alternatively, a WAF rule that blocks POST requests to wp-admin/admin-ajax.php with action=search-user from non-administrator roles can suppress exploitation without affecting other plugin functionality, though rule crafting and testing is required to avoid breaking legitimate admin workflows.
