The Search Simple Fields plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 0.2. This is due to missing or incorrect nonce validation on the search simple fields options() function in functions admin.php. This makes it possible for unauthenticated attackers to modify the plugin's settings — including post types to search in, custom fields, media fields and the custom media function name — via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
