League Table <= 1.13 - Cross-Site Request Forgery

The League Table plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.13. This is due to missing or incorrect nonce validation in the view/tables.php file. This makes it possible for unauthenticated attackers to clone, edit, update, and delete tables via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
