CVE-2026-6220Network attack vector

Authenticated SSRF via streamIp manipulation

Published Apr 13, 2026 · Updated Apr 13, 2026

Server-side request forgery in HummerRisk 1.5.0 and earlier allows remote authenticated users to reach network locations via streamIp. The CNA identifies ServerService.addServer as the locus but does not explain how streamIp reaches an outbound request; its cited proof of concept instead documents stored XSS through publicKey. Administrative privileges are required under the CNA assessments, and the attributed SSRF mechanism remains unverified.
