Description

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.
