## Description

The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Full Path Disclosure via the 'debug' parameter in all versions up to, and including, 1.4.9, due to the plugin turning on full error reporting and display_errors for any admin-context request with 'debug=on' in the query string, including requests to admin-ajax.php and admin-post.php that do not require authentication. This makes it possible for unauthenticated attackers to have PHP errors and warnings displayed, which can reveal the full server path of the web application and other details.
