Cotonti through 1.0.0 contains a cross-site request forgery vulnerability in admin.users.php that allows attackers to delete user groups without token verification. Attackers can craft malicious links or pages that trick authenticated administrators into deleting custom groups and their associated permissions by riding the administrator's session.
