Transporters.io <= 2.1.1 - Cross-Site Request Forgery to Stored Cross-Site Scripting

The Transporters.io plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.1. This is due to missing nonce validation on a function. This makes it possible for unauthenticated attackers to inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
