In Splunk Enterprise versions below 9.3.1, and 9.2.0 versions below 9.2.3, and Splunk Cloud Platform versions below 9.2.2403.103, 9.1.2312.200, 9.1.2312.110 and 9.1.2308.208, a low-privileged user that does not hold the "admin" or "power" Splunk roles could run a search as the "nobody" Splunk user in the SplunkDeploymentServerConfig app. This could let the low-privileged user access potentially restricted data.
