WP Simple Spreadsheet Fetcher for Google < 0.3.7 - Cross-Site Request Forgery

The WP Simple Spreadsheet Fetcher for Google plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions before 0.3.7. This is due to missing or incorrect nonce validation on the render_settings function. This makes it possible for unauthenticated attackers to arbitrarily change plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
