I may be wrong, but I think the problem is that on a shared host, 
the IP address will be 127.0.0.1 when accessing a site on the same 
machine.

Consider this scenario:

     1) symfony developer has site example.org on host ABC
     2) hacker has site foobar.com on host ABC
     3) hacker puts the script
          
          <?php
          echo file_get_contents('http://example.org/frontend_dev.php') 
          ?>

     on his account
     4) PHP makes the request, but because it's the same machine, 
     the remote address is 127.0.0.1
     5) symfony thinks it's safe to display frontend_dev, so it does

I doubt this happens every day, but I suppose it's possible.
