The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the do_updatecar and createcar functions in all versions up to, and including, 1.4.3. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server, which may make remote code execution possible.
The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.2. This is due to missing or incorrect nonce validation on the 'save' function. This makes it possible for unauthenticated attackers to change plugin access privileges via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation allows attackers with subscriber-level privileges and above to upload arbitrary files on the affected site's server which may make remote code execution possible.
