Does this matter?

Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.

Description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.10, 3.9.24, and 3.8.71, a user who holds a Splunk role with permissions to list storage passwords but does not hold Splunk Secure Gateway administration privileges could access Mobile Device Management signing secrets that compromise all affected mobile-device enrollment trust through Splunk Secure Gateway. The vulnerability is possible because Splunk Secure Gateway Representational State Transfer (REST) API endpoints for deployment bundle, Security Assertion Markup Language setup, and companion app workflows do not require Splunk Secure Gateway administration privileges before processing requests.
