Could you provide a minimized test case?
The provided page appears to be https://gallery.technet.microsoft.com/scriptcenter/VB-Script-to-Check-and-620579cd, which is a download page on Microsoft TechNet.

I don't see the endless refresh behaviour. Are you sure you don't have an extension installed that is causing the refreshes?

Refreshing the browser isn't a security bug.
Status: WontFix (was: Unconfirmed)
This is working as intended. It has nothing to do with VBScript in the page, and is caused by the following JavaScript in Documentation.html:

if (top.location == self.location) {                         
    window.location.replace(window.location.href.replace('/description', ''));
}

This page creates an endless navigation loop.
Awesome. You guys are as good as I expected. Thanks for looking into this.
