9to5 Mac reports that the vulnerability was discovered by developer Lemi Orhan Ergin and he publicly contacted Apple Support to report the flaw.
The implications of this bug can be disastrous since an authorized user can exploit the flaw and can change user privileges, reset passwords and view personal files without having administrator privileges.
