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 walletparam object on the standard WooCommerce My Account page, which is accessible to any authenticated user, making it trivially obtainable by a Subscriber.

The Wallet for WooCommerce plugin for WordPress is vulnerable to SQL Injection via the 'search[value]' parameter in all versions up to, and including, 1.5.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Wallet for WooCommerce plugin for WordPress is vulnerable to incorrect conversion between numeric types in all versions up to, and including, 1.5.6. This is due to a numerical logic flaw when transferring funds to another user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create funds during a transfer and distribute these funds to any number of other users or their own account, rendering products free. Attackers could also request to withdraw funds if the Wallet Withdrawal extension is used and the request is approved by an administrator.
