What is CVE-2026-12103?
CVE-2026-12103 is a medium-severity missing authorization vulnerability in subratamal Wallet for WooCommerce, published on 11 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
