CVE-2026-20266: OS Command Injection in the btool Configuration Helper in Splunk AI Toolkit
Critical · CVSS 9.1 (CVSS 3.1)EPSS 0.63%, 50th percentilePublished Updated Assigner: cisco
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.
