CVE-2026-76399: Splunk ai toolkit incorrect permission assignment vulnerability

Splunk · Ai Toolkit

In Splunk AI Toolkit versions below 6.0.1, a user who holds the "power" Splunk role could modify app-provided scheduled searches to run arbitrary Search Processing Language (SPL) using the permissions of the search owner, which could allow access to all relevant data and affect system integrity. The vulnerability is possible because Splunk AI Toolkit gives the "power" Splunk role permission to modify scheduled searches that run using the permissions of the search owner.
