OS Command Injection in Splunk AI Toolkit btool Configuration Helper
CVE-2026-20266 is a critical OS command injection vulnerability in the btool configuration helper of Splunk AI Toolkit. It affects Splunk AI Toolkit versions below 5.7.4. The flaw is caused by an unsafe shell execution pattern in which the helper constructs operating system command strings from dynamic parameters without disabling shell interpretation. As a result, a user holding the Splunk "admin" role can cause arbitrary OS commands to be executed on the host running the Splunk Enterprise instance.
