CVE-2025-20368 is a cross-site scripting vulnerability in Splunk Enterprise and Splunk Cloud Platform. In Splunk Enterprise versions prior to 9.4.4, 9.3.6, and 9.2.8, and Splunk Cloud Platform versions prior to 9.3.2411.108, 9.3.2408.118, and 9.2.2406.123, a low-privileged user without the admin or power roles can craft a malicious payload through the error messages and job inspection details of a saved search. When this attacker-controlled content is later rendered in another user’s browser, it can trigger unauthorized JavaScript execution in the context of the Splunk web interface. The issue is consistent with a stored XSS condition involving insufficient neutralization of untrusted data before it is included in web content.
