CVE-2026-20266

Splunk Ai Toolkit command injection

9.1 CRITICALEPSS 0.63%
  1. Published17 Jun 2026

Description

In Splunk AI Toolkit versions below 5.7.4, a user who holds the "admin" Splunk role could execute arbitrary OS commands on the host running the Splunk Enterprise instance. The vulnerability is possible because of an unsafe shell execution pattern in the btool configuration helper, which constructs OS command strings from dynamic parameters without disabling shell interpretation.
