      "value": "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."

      "value": "El plugin Oliver POS - Un Punto de Venta (POS) de WooCommerce para WordPress es vulnerable a la Omisión de autorización mediante clave controlada por el usuario en todas las versiones hasta la 2.4.2.6 inclusive. El plugin protege todo su espacio de nombres de la API REST /wp-json/pos-bridge/* a través de la función de devolución de llamada de permiso oliver_pos_rest_authentication(), que utiliza una comparación PHP laxa (==) para comparar el valor del encabezado 'OliverAuth' proporcionado por el atacante con la opción 'oliver_pos_authorization_token'. En instalaciones nuevas donde el administrador aún no ha completado el flujo de conexión, esta opción no está configurada (get_option devuelve falso). Debido a la manipulación de tipos de PHP, la comparación laxa '0' == false se evalúa como verdadera, permitiendo a un atacante no autenticado omitir la autenticación enviando 'OliverAuth: 0'. Esto otorga acceso completo a todos los puntos finales de la API de POS, permitiendo a los atacantes leer datos de usuario (incluidos los detalles del administrador), actualizar perfiles de usuario (incluidas las direcciones de correo electrónico) y eliminar usuarios no administradores. Un restablecimiento de correo electrónico de cuenta de administrador puede llevar a la toma de control del sitio."
