The Edge Processor feature is turned off by default.\nFor more information see Set up a data management control plane (https://help.splunk.com/en/splunk-enterprise/process-data-at-the-edge/use-edge-processors-for-splunk-enterprise/10.4/getting-started/set-up-a-data-management-control-plane) and Getting sample data for previewing data transformations (https://help.splunk.com/en/splunk-enterprise/process-data-at-the-edge/use-edge-processors-for-splunk-enterprise/10.4/working-with-pipelines/getting-sample-data-for-previewing-data-transformations) in the Splunk documentation.\n\n## Affected\n\n- `enterprise >= 10.4 < 10.4.4`\n\n## Remediation\n\nUpgrade Splunk Enterprise to versions 10.4.4, 10.2.8, 10.0.11, and 9.4.16 or higher.\n\n### Workarounds\n\nTurn off the SPL2 preview sidecar by setting `spl2_preview_enabled` to `false` in the `server.conf` configuration file if you do not use SPL2 previews for Edge Processor pipelines. Restart Splunk Enterprise for the change to take effect.\nFor more information see the [server.conf configuration specification file](https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.4/configuration-file-reference/10.4.4-configuration-file-reference/server.conf) in the Splunk documentation.","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":29.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
