Summary
The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'poplink' parameter in all versions up to, and including, 1.4.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The handler requires only a WordPress nonce (vikwp_nonce), which the plugin itself emits to unauthenticated visitors on the public booking-confirmation page, allowing an attacker to obtain a valid token without any account.
