{"id":"CVE-2026-76398","state":"PUBLISHED","title":"Improper Access Control during Experiment History Deletion through the REST API in Splunk AI Toolkit","description":"In Splunk AI Toolkit versions below 6.0.1, a user who does not hold the \"admin\" or \"power\" Splunk roles could delete the experiment history of another user without permission through the Representational State Transfer (REST) API. The vulnerability is possible because Splunk AI Toolkit deletes experiment history before it verifies that the user can delete the associated experiment.
