The CLUEVO LMS, E-Learning Platform plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.13.2. This is due to missing or incorrect nonce validation on the cluevo_render_module_ui() function. This makes it possible for unauthenticated attackers to delete modules via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
