Path Traversal Allows SPL Injection Bypass in Splunk Enterprise

Publication date: 2026-02-18

Last updated on: 2026-02-20

Assigner: Cisco Systems, Inc.

Description
In Splunk Enterprise versions below 10.2.0, 10.0.3, 9.4.5, 9.3.7, and 9.2.9, and Splunk Cloud Platform versions below 10.1.2507.0, 10.0.2503.9, 9.3.2411.112, and 9.3.2408.122, a low-privileged user who does not hold the "admin" or "power" Splunk roles could bypass the SPL safeguards for risky commands when they create a Data Model that contains an injected SPL query within an object. They can bypass the safeguards by exploiting a path traversal vulnerability.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Splunk Enterprise or Splunk Cloud Platform to the fixed versions: Splunk Enterprise 10.2.0, 10.0.3, 9.4.5, 9.3.7, or 9.2.9, or the corresponding fixed versions for Splunk Cloud Platform.

As a temporary workaround, disabling Splunk Web can prevent exploitation of this vulnerability.

Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-20137 is a low-severity vulnerability affecting certain versions of Splunk Enterprise and Splunk Cloud Platform. It involves a path traversal flaw that allows a low-privileged user, who does not have "admin" or "power" roles, to bypass safeguards on risky SPL commands by creating a Data Model containing an injected SPL query within an object.'}, {'type': 'paragraph', 'content': 'When a high-privileged user opens this object, the injected SPL query executes with their privileges, potentially exposing sensitive information without authorization. Exploitation requires tricking the high-privileged user into initiating a request in their browser, so it cannot be exploited arbitrarily by the attacker.'}] [1]

Impact Analysis

This vulnerability can lead to unauthorized exposure of sensitive information because the injected SPL query executes with the privileges of a high-privileged user when they open the malicious Data Model object.

An attacker with low privileges can exploit this by tricking a high-privileged user to open the crafted object, which may result in information disclosure without proper authorization.
