Description

The Coming Soon & Maintenance Mode Page plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.57. This is due to missing or incorrect nonce validation on the save_meta_box() function. This makes it possible for unauthenticated attackers to save meta boxes via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
