CVE-2026-76257Missing Authorization through REST API Endpoints in Splunk Secure Gateway

Updated under an hour ago ()

Does this affect you?

It affects Splunk Enterprise and 3 other products. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
