Cross Site Scripting vulnerability in broker v8.1.2.1

We are currently running v8.1.2.1 of the SAM suite and I was just notified by my compliance team that they have detected an XSS vulnerability on the server running my broker.  We are unable to upgrade to the latest version at this time, so I have two questions: 1) is the vulnerability fixed in a later version of the software?  Is there a workaround to mitigate the vulnerability in 8.1.2.1?  Thanks for any help.
