## How to fix

- Fixed in 2.0.1

## Technical details

The vulnerability is a cross-site request forgery (CSRF) flaw in the skill management AJAX endpoint (skill.ajax.php) where actions like add, delete_gradebook_from_skill, save_profile, and delete_profile lack Security::check_token() validation. An authenticated administrator or DRH is vulnerable if they visit a malicious page while logged in; the attacker's page can issue requests to the AJAX endpoint to mutate skill and gradebook data. The fix adds CSRF token validation to protect these AJAX operations.
