Splunk AI Toolkit 5.7.4 Allows Low-Privileged Users to Exfiltrate Data via HTTP
CVE-2026-20265 Published on June 17, 2026
Insecure Default Domain Allowlist in Splunk AI Toolkit
In Splunk AI Toolkit versions below 5.7.4, a low-privileged user that does not hold the "admin" or "power" Splunk roles could cause the Splunk AI Toolkit to make outbound requests over HTTP to a server that an attacker controls, which could allow for data exfiltration.
The vulnerability exists because of an insecure default domain allowlist in the Splunk AI Toolkit, which does not restrict outbound AI agent requests to approved external domains.
Weakness Type
Insecure Default Initialization of Resource
The software initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.
