Restricting access to DOM

[kickASS28]

Hi,

I have an HTML template in my report, in that template if I try to access the document object modal, I am able to do that.

<svg onload=alert(document.domain)></svg>

Here I want to restrict access to documents from the template, how can I configure that?

This is more of a general html/js question. I am afraid HTML/browsers don't have such a feature.
