Tabs <= 4.0.3 is vulnerable to Cross Site Request Forgery (CSRF) to Stored XSS vulnerability

The WordPress Tabs plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.0.3. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update settings and 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.
