Descriptions

The Five Star Restaurant Reservations WordPress plugin before 2.4.8 does not have capability and CSRF checks in the rtb_welcome_set_schedule AJAX action, allowing any authenticated users to call it. Due to the lack of sanitisation and escaping, users with a role as low as subscriber could perform Cross-Site Scripting attacks against logged in admins

El plugin Five Star Restaurant Reservations de WordPress versiones anteriores a 2.4.8, no presenta comprobaciones de capacidad y CSRF en la acción AJAX rtb_welcome_set_schedule, permitiendo que cualquier usuario autenticado la llame. Debido a una falta de saneo y escape, los usuarios con un rol tan bajo como el de suscriptor podrían llevar a cabo ataques de tipo Cross-Site Scripting contra administradores conectados
