Advisory ID: SVD-2026-0301
CVE ID: CVE-2026-20162
Published: 2026-03-11
Last Update: 2026-03-11
CVSSv3.1 Score: 6.3, Medium
CVSSv3.1 Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N
CWE: CWE-79
Bug ID: VULN-50292
Description
In Splunk Enterprise versions below 10.2.0, 10.0.3, 9.4.9, and 9.3.9, and Splunk Cloud Platform versions below 10.2.2510.4, 10.1.2507.15, 10.0.2503.11, and 9.3.2411.123, a low-privileged user who does not hold the “admin” or “power” Splunk roles could craft a malicious payload when creating a View (Settings - User Interface - Views) at the /manager/launcher/data/ui/views/_new endpoint leading to a Stored Cross-Site Scripting (XSS) through a path traversal vulnerability. This could result in execution of unauthorized JavaScript code in the browser of a user.
The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.
Solution
Upgrade Splunk Enterprise to versions 10.2.0, 10.0.3, 9.4.9, 9.3.9, or higher.
Splunk is actively monitoring and patching Splunk Cloud Platform instances.
