Input validation vulnerability in CLUEVO LMS, E-Learning Platform 1.13.2

The CLUEVO LMS, an E-Learning Platform for WordPress, has a security issue that allows unauthorized individuals to delete modules. This vulnerability is present in all versions of the plugin up to 1.13.2. It occurs because the cluevo_render_module_ui() function does not properly validate nonces. This means that attackers who are not logged in can manipulate a site administrator into clicking on a link, which will then allow them to delete modules through a fake request.
