FameTheme Demo Importer <= 1.1.5 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The FameTheme Demo Importer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.5. This is due to missing or incorrect nonce validation on the ajax_import function. This makes it possible for unauthenticated attackers to import demo content and change the active theme, including invalid themes, resulting in Denial of Service, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
