CVE-2026-76398 is a medium severity vulnerability in Splunk AI Toolkit version 6.0 where users without admin or power roles can delete other users' experiment history via the REST API. This occurs because the software deletes experiment history before verifying user authorization. No official patch or remediation level is stated in the available data.
AI Analysis
Technical Summary
In Splunk AI Toolkit versions below 6.0.1, specifically version 6.0, a lack of proper authorization checks allows users without the 'admin' or 'power' roles to delete experiment history belonging to other users through the REST API. The vulnerability arises because the deletion of experiment history is performed prior to verifying that the user has permission to delete the associated experiment. This improper authorization check could lead to unauthorized modification of experiment data.
Potential Impact
The vulnerability allows unauthorized users with limited privileges to delete experiment history of other users, resulting in integrity loss of experiment data. There is no impact on confidentiality or availability reported. The CVSS score of 4.3 (medium) reflects the limited scope and impact of this issue.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the REST API to trusted users and monitor usage for unauthorized deletion attempts. Follow Splunk's documentation and updates regarding Experiment Assistants for any official patches or workarounds.
