CVE-2026-76397: The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. in Splunk Splunk AI Toolkit
CVE-2026-76397 is a high-severity vulnerability in Splunk AI Toolkit versions below 6.0.0. It allows a user with the "power" Splunk role to access and delete experiment history data belonging to other users by modifying the key value identifying the data. This occurs because the toolkit does not maintain the trusted experiment scope when processing caller-controlled query values, leading to unauthorized data access and deletion.
AI Analysis
Technical Summary
In Splunk AI Toolkit versions prior to 6.0.0, the authorization mechanism fails to enforce proper access controls on experiment history data. Specifically, a user with the "power" role can manipulate the key identifying experiment data, bypassing restrictions and gaining access to or deleting data associated with other users. This vulnerability arises from the toolkit not preserving the trusted experiment scope during query processing, allowing unauthorized access to restricted history data.
Potential Impact
An attacker with the "power" Splunk role can access and delete experiment history data belonging to other users. This compromises data confidentiality and integrity within the Splunk AI Toolkit environment. The vulnerability does not affect availability. There are no known exploits in the wild as of the published date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict the assignment of the "power" role to trusted users only and monitor for any unauthorized access attempts related to experiment history data.
