Summary
In Splunk SOAR versions below 8.6.0, an authenticated user with no role assigned could use the /rest/health endpoint to gather system and cluster telemetry that should be restricted to administrative or support users.
The vulnerability is a missing authorization check, where the endpoint does not verify that the caller holds a role permitted to view system health and cluster state. For more information see Manage roles and permissions in Splunk SOAR (On-premises) ( ) and Monitor the health of your Splunk SOAR (On-premises) system ( ) in the Splunk documentation.
