CVE-2026-76325

Splunk Splunk

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the "power" Splunk role could store a malicious ui-tour knowledge object that matches an auto-tour page name and share the object at the app level. The object can execute arbitrary JavaScript in the browser of another authenticated user who visits a standard Splunk Web page. The JavaScript could expose all relevant data and affect system integrity within the second user permissions. The Cross-Site Scripting (XSS) vulnerability is possible because Splunk Web resolves auto-tour entries from the app namespace and uses untrusted tour content when building the tour image.
