Input validation vulnerability in Seo Monster 3.3.3

The Seo Monster plugin for WordPress has a security issue called Cross-Site Request Forgery. This can happen in all versions, including 3.3.3. The problem is with the check_integration() function, which doesn’t properly check for a security code called a nonce. Because of this, someone without permission can change settings and add harmful code to a website by tricking the website administrator into clicking on a link.
