 "title": "VikRentCar Car Rental Management System <= 1.4.9 - Unauthenticated Stored Cross-Site Scripting via Custom Field Name and Popup Link",
 "description": "The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name' and 'poplink' parameters of the terms-of-service custom field saving task (customf.savetosajax) in versions 1.4.0 up to, and including, 1.4.9, due to a missing capability and admin-context check on that task, which is also processed on front-end requests and is protected only by a nonce printed on public pages, combined with insufficient output escaping of custom field names and popup links. This makes it possible for unauthenticated attackers to modify any custom field and inject arbitrary web scripts in pages that will execute whenever a user accesses the car details or order confirmation pages.",
