@douglashurd I put in an app install request for this Add On in Splunk Cloud. They said it failed vetting and gave me the reasons. If you'd like to contact me, I'll send you what they said is vulnerable.
The Splunk team has approved the app for Cloud. The issue comes down to a .py file that we use per Splunk's older guidance which has since been deprecated. There is no suitable replacement for the file currently.
