The Oliver POS – A WooCommerce Point of Sale (POS) plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.4.2.6. The plugin protects its entire /wp-json/pos-bridge/* REST API namespace through the oliver pos rest authentication() permission callback, which uses a loose PHP comparison (==) to compare the attacker-supplied 'OliverAuth' header value against the 'oliver pos authorization token' option. On fresh installations where the admin has not yet completed the connection flow, this option is unset (get option returns false). Due to PHP's type juggling, the loose comparison '0' == false evaluates to true, allowing an unauthenticated attacker to bypass authentication by sending 'OliverAuth: 0'. This grants full access to all POS API endpoints, enabling attackers to read user data (including administrator details), update user profiles (including email addresses), and delete non-admin users. An admin account email reset can lead to site takeover.
