Input validation vulnerability in Simple SEO 2.0.23

The Simple SEO plugin for WordPress is vulnerable to a security issue. This means that a malicious person could trick a site administrator into performing certain actions (such as clicking on a link) without the administrator knowing. This could allow the malicious person to import content from other plugins, as well as generate and delete sitemaps. This vulnerability affects all versions of the Simple SEO plugin up to and including version 2.0.23. This is because the plugin does not use the proper security measures to protect against this type of attack.
