Wsify Widget <= 1.0 is vulnerable to CSRF to Stored XSS vulnerability

The Wsify Widget plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update the plugin's 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.
