"id" argument is not sanitized before to be used in a sql query...
also you can inject sql statements regardless of magic_quotes_gpc settings,
look at undoMagic() function in vars4.1.0.php:
// removes magic quotes if that option is enabled
function undoMagic($data) {
return get_magic_quotes_gpc() ? stripslashes($data) : $data;
}
very nice code :)
