WP MultiTasking <= 0.1.12 is vulnerable to Multiple CSRF vulnerability

The WP MultiTasking – WP Utilities plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.1.12. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update the SMTP settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
