Chamilo LMS is a learning management system. Prior to 1.11.38, Twig template files (.tpl) under /main/template/default/ are directly accessible without authentication via HTTP GET requests. These templates expose internal application logic, variable names, AJAX endpoint URLs, and admin panel structure. This vulnerability is fixed in 1.11.38.
