| Description | In Splunk AI Toolkit versions below 6.0.0, a low-privileged user who does not hold the "admin" or "power" Splunk roles could start, stop, and configure containers, and read or modify connection and configuration data through the Representational State Transfer (REST) API. The missing authorization is possible because multiple REST API handlers in Splunk AI Toolkit do not enforce authorization checks.

Additional Advisory Data
Solutions
CNA: Upgrade each affected Splunk app or add-on to the applicable fixed version listed in Product Status.
Workarounds
CNA: 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.
