Vulnerability Title
Insecure Default Domain Allowlist in Splunk AI Toolkit
Source: CVE Program / CVE List V5
Vulnerability Description
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.
