Answer in brief
CVE-2026-20266 records a Critical severity (CVSS 9.1) vulnerability in OS Command Injection in the btool Configuration Helper in Splunk AI Toolkit. The current sources do not mark it as known exploited. The current feed maps Splunk/Splunk AI Toolkit (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
