  title: Shodan CVEDB Product Vulnerability Enrichment
  summary: Resolve a product to a CPE, search its CVEs, then pull full CVE details.
  description: >-
    A vulnerability research pattern over the free CVEDB. The workflow looks up
    the CPE 2.3 dictionary entries for a product, searches the CVE catalog for
    vulnerabilities affecting that product ordered by exploitation likelihood,
    and then retrieves the full record for the top CVE. CVEDB is unauthenticated
    so no API key is required. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.

  summary: Enumerate CPEs and CVEs for a product and detail the top CVE.
  description: >-
    Searches the CPE dictionary for a product, searches the CVE catalog for that
    product ordered by EPSS, and retrieves the full details for the top CVE.
  inputs:
    type: object
    required:
    - product
    properties:
      product:
        type: string
        description: The product name to research (e.g. "nginx").
      isKev:
        type: boolean
        description: Restrict CVE results to CISA Known Exploited Vulnerabilities.
        default: false
      cveId:
        type: string
        description: >-
          The CVE identifier to detail. CVEDB search returns a list keyed by
          position, so the chosen CVE id is carried forward through this input
          for the detail lookup.
