Smart Maintenance Mode <= 1.4.4 - Cross-Site Request Forgery

Description The Smart Maintenance Mode plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.4. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action granted they can trick a site administrator into performing an action such as clicking on a link.
