Official description

Chamilo LMS is an open-source learning management system. Prior to 2.0.1, the `add`, `delete_gradebook_from_skill`, `save_profile`, and `delete_profile` actions in `public/main/inc/ajax/skill.ajax.php` perform database mutations without `Security::check_token()` validation. An attacker can use cross-site request forgery to cause an authenticated administrator or DRH who visits a malicious page to create, modify, or delete skill records and profiles, or remove skill-gradebook associations. This issue is fixed in version 2.0.1.
