Summary

The AuthorSure plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.3. This is due to missing or incorrect nonce validation on the 'authorsure' page. 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.
