Add warning about WSRP issue:

"Portlet rendering over WSRP may randomly fails ending up with the following error that can be found in the log:
javax.jcr.ItemNotFoundException: FATAL: Parent is null
A refresh of the page would temporarly fix the issue. We are currently working on a fix." 

Ensure the following two security issues are documented:

XSS issues passed in URL
https://jira.jboss.org/browse/GTNPORTAL-1667 is the most critical IMO and also very difficult to fix without a clear understanding of the URL encoding. It will need immediate attention, I had a look into it, the problem is that the portal is rendering URLs by taking the current URL as-is, allowing anyone to execute XSS.

Gadget proxy can serve as anonymous proxy
https://jira.jboss.org/browse/GTNPORTAL-1666 

Closing old ticket.
