Access violation vulnerability in Five Star Restaurant Menu and Food Ordering 2.4.16

The Restaurant Menu and Food Ordering plugin for WordPress has a security vulnerability that allows unauthorized users to create new data without permission. This issue affects all versions up to 2.4.16 and is caused by a lack of check for capabilities in functions like ‘add_section’, ‘add_menu’, ‘add_menu_item’, and ‘add_menu_page’. This means that attackers who are logged in with at least Subscriber-level access can create menu sections, menus, food items, and new menu pages without proper authorization.
