Description

In Splunk Enterprise versions below 9.4.3, 9.3.5, 9.2.7, and 9.1.10, a low-privileged user that does not hold the "admin" or "power" Splunk roles could turn off the scheduled search `Bucket Copy Trigger` within the Splunk Archiver application. This is because of missing access controls in the saved searches for this app.
