In Splunk Enterprise versions below 10.4.2 and 10.2.6, a user who does not hold the "admin" or "power" Splunk roles could delete Splunk Processing Language version 2 (SPL2) modules belonging to other users through the data management orchestrator interface. The vulnerability does not affect Splunk Enterprise versions below 10.2. The broken object level authorization is possible because the data management orchestrator does not verify that the requesting user owns the target resources before it deletes the modules. For more information see Manage SPL2-based apps (https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/meet-splunk-apps/manage-spl2-based-apps) in the Splunk documentation.
