CVE-2026-76342

MEDIUM 5.4

Published 2026-08-19 · Last modified 2026-08-19

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.

What an attacker needs

  • Access: Reachable over the network — no local access needed
  • Privileges: Requires a low-privilege account
  • User interaction: A user must take an action (click / open a file)
  • Complexity: Needs a race window or specific setup
