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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • webfactory Under Construction — Up to and including 3.96
  • webfactoryltd under_construction — Up to and including 3.96
