CVE-2026-76397— Improper Access Control in Experiment History through the REST API in Splunk AI Toolkit

Quick assessment

Affected
Splunk Splunk AI Toolkit
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Splunk AI Toolkit 6.0.0 之前的版本中，拥有“power”角色的 Splunk 用户能够访问并删除实验历史中的所有相关数据，包括与其他用户关联的数据。出现该漏洞的原因是，Splunk AI Toolkit 在处理由调用方控制的查询值之前，未保留可信的实验作用域（trusted experiment scope），从而导致在访问受限的历史数据时未能进行正确授权控制。有关更多信息，请参阅 Splunk 文档中的“实验助手”（Experiment Assistants）部分：https://he

Vulnerability Title
Improper Access Control in Experiment History through the REST API in Splunk AI Toolkit
Source: CVE Program / CVE List V5
Vulnerability Description
In Splunk AI Toolkit versions below 6.0.0, a user who holds the "power" Splunk role could access and delete all relevant data in experiment history, including data associated with other users. 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. For more information see Experiment Assistants (https://help.splunk.com/en/splunk-cloud-platform/apply-machine-learning/use-ai-toolkit/5.6.4/experiment-assistants) in the Splunk documentation.
