CVE-2026-76342: Risky Commands Safeguards Bypass through Splunk Web in Splunk Enterprise

Published Aug 19, 2026
·
Updated

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 risky Search Processing Language (SPL) commands in a Table Editor dataset and share the dataset. A user who holds the "admin" Splunk role triggers the commands when that user opens the dataset in the Table Editor. The commands run using the permissions of the second user and could expose all relevant data and modify lookup files. The vulnerability is possible because the Table Editor does not apply SPL safeguards for risky commands to the field-summary search that it runs for the Initial Data step. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the "power" Splunk role should not be able to exploit the vulnerability at will. For more information see SPL safeguards for risky commands (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/best-practices-for-splunk-platform-security/spl-safeguards-for-risky-commands) and Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.

Frequently Asked Questions

1

Which users and workflows are involved in exploitation?

A user with the Splunk "power" role must be able to create and share a Table Editor dataset containing risky SPL commands. An "admin" role user must then open that dataset in Table Editor, specifically causing the Initial Data step's field-summary search to run.

2

Can a power-role user exploit this directly whenever they want?

No. The power-role user cannot exploit the issue at will; exploitation requires phishing an affected admin user into initiating a request in their browser and opening the shared dataset.

3

What could happen if the attack succeeds?

The risky SPL commands run with the admin user's permissions. This could expose all data available to that user and modify lookup files.

4

What versions are affected?

Affected versions are Splunk Enterprise releases below 10.4.2, 10.2.6, 10.0.9, and 9.4.14.
