Schema – All In One Schema Rich Snippets <= 1.6.5 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Schema - All In One Schema Rich Snippets plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.6.5. This is due to missing or incorrect nonce validation on the rich_snippet_dashboard function. This makes it possible for unauthenticated attackers to perform unauthorized configuration updates via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
