CVE-2023-0831 Information

Description

The Under Construction plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 3.96. This is due to missing or incorrect nonce validation on the dismiss_notice function called via the admin_action_ucp_dismiss_notice action. This makes it possible for unauthenticated attackers to dismiss plugin notifications via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
