CVE-2026-20266: The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. in Splunk Splunk AI Toolkit
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.
AI Analysis
Technical Summary
The vulnerability in Splunk AI Toolkit versions equal to 5.7 arises from an unsafe shell execution pattern in the btool configuration helper. This component constructs OS command strings from dynamic parameters without disabling shell interpretation, enabling an admin user to execute arbitrary OS commands on the underlying host. The issue is due to improper neutralization of special elements in externally-influenced input used to build OS commands, leading to command injection.
Potential Impact
An attacker with admin privileges on Splunk AI Toolkit 5.7 can execute arbitrary operating system commands on the host running Splunk Enterprise. This can lead to full compromise of the system, including unauthorized data access, modification, or destruction, and disruption of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict admin role assignments to trusted users only and monitor for suspicious activity related to command execution. Avoid running Splunk AI Toolkit 5.7 in environments where untrusted users have admin access.
