CVE-2026-76397 Published on August 19, 2026
Improper Access Control in Experiment History through the REST API in Splunk AI Toolkit

The vulnerability is possible because Splunk AI Toolkit does not preserve the trusted experiment scope when it processes caller-controlled query values before accessing restricted history data.
