 "title": "VikRentCar Car Rental Management System <= 1.4.10 - Unauthenticated Stored Cross-Site Scripting via Booking Optionals",
 "description": "The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the optionals (car options) data submitted in the front-end booking flow in all versions up to, and including, 1.4.10. This is due to insufficient input sanitization of the submitted option id:quantity pairs and missing output escaping when the stored quantity is rendered in the administrator's edit-booking view. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute whenever an administrator opens the affected booking.",
