## Description

The CCI Posts Carousel All In One plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.0 due to the permission check for the wp-posts-carousel/v1/admin REST routes being evaluated when routes are registered, before REST cookie authentication and nonce validation, so a privileged user's session cookie alone authorizes requests. This makes it possible for unauthenticated attackers to create, update, delete or duplicate carousels and change plugin settings via a forged request, granted they can trick a logged-in site administrator into performing an action such as clicking a link.
