WP Online Users Stats <= 1.0.0 - Cross-Site Request Forgery to Stored Cross-Site Scripting via hk_dataset_results Function

The WP Online Users Stats plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.0. This is due to missing nonce validation within the hk_dataset_results() 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.
