Vulnerability Details : CVE-2023-0831
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.
