Alert meAnalysisAIv1 – Mar 12, 2026
Stored XSS via path traversal in Splunk Enterprise and Cloud Platform allows low-privileged users to inject malicious JavaScript into Views, compromising any user who visits the affected page. An attacker must socially engineer a victim into initiating the malicious request, but no special privileges or user interaction beyond initial page load is required. Affected versions include Splunk Enterprise below 10.2.0, 10.0.3, 9.4.9, and 9.3.9, with no patch currently available.
Earlier versions of this analysis (1)
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. [CVSS 6.3 MEDIUM]
RemediationAI
Monitor vendor advisories for a patch. Implement output encoding and Content Security Policy headers. Restrict network access to the affected service where possible.

DescriptionCVE.org
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.
Executive ViewAI
Organizations using Splunk Enterprise should be aware of moderate risk from CVE-2026-20162, a cross-site scripting vulnerability rated CVSS 6.3. Attackers could inject scripts to steal sessions or perform actions as authenticated users. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: implement CSP headers, enable HttpOnly cookies, deploy WAF XSS rules.

How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
Cross-Site Scripting occurs when an application accepts untrusted data and sends it to a web browser without proper validation or encoding.
Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.
