  "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 :)
