CVE-2026-76391
Improper Privilege Management through Agent Run History in Splunk AI Toolkit
- Published
- Updated
- Reserved
- Assigned by
- cisco
Description
In Splunk AI Toolkit versions below 6.0.0, a user who does not hold the "admin" or "power" Splunk roles could run searches with system-level privileges, access all relevant data, affect system integrity, and read or delete search jobs belonging to other users through Agent Run History. The improper privilege management is possible because the Agent Run History handler replaces the calling user session key with a system authentication token before it performs search operations. For more information see AI Toolkit Agent Launchpad (https://help.splunk.com/en/splunk-enterprise/apply-machine-learning/use-ai-toolkit/6.0.0/ai-toolkit-connections-containers-and-agents/ai-toolkit-agent-launchpad) in the Splunk documentation.

What to do
Solution: Upgrade each affected Splunk app or add-on to the applicable fixed version listed in Product Status.
Workaround: Turn off or remove the Splunk AI Toolkit app. For more information see [Manage app and add-on objects](https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.2/meet-splunk-apps/manage-app-and-add-on-objects) in the Splunk documentation. Note: turning off Splunk AI Toolkit turns off AI Toolkit Search Processing Language (SPL) commands and model operations. Splunk App for Data Science and Deep Learning and custom search commands that depend on AI Toolkit models or APIs might stop functioning. Unrelated Splunk custom search commands are not affected. For more information see [Troubleshoot the Splunk Machine Learning Toolkit](https://help.splunk.com/en/splunk-cloud-platform/apply-machine-learning/use-ai-toolkit/5.5.0/troubleshooting-mltk/troubleshoot-the-splunk-machine-learning-toolkit) and [DSDL install/version dependencies](https://help.splunk.com/en/splunk-enterprise/apply-machine-learning/splunk-app-for-data-science-and-deep-learning/5.1/install-and-configure-the-splunk-app-for-data-science-and-deep-learning/install-or-upgrade-the-splunk-app-for-data-science-and-deep-learning) in the Splunk documentation.
