  Explorium publishes NO vulnerability disclosure programme. This file records a
  verified absence, not a hit - it exists so the gap is legible rather than
  looking un-checked. No Security pointer is emitted in apis.yml, because there
  is no disclosure or security-policy page to point at.

    The one security page that exists is compliance marketing. It names no
    security contact, no reporting channel and no disclosure policy. The only
    published address on the whole domain is privacy@explorium.ai, which is a
    privacy contact, not a vulnerability channel.
remediation: >-
  The cheapest fix available to Explorium: publish a four-line
  /.well-known/security.txt with Contact and Policy fields. It is the missing
  piece in an otherwise strong /.well-known/ surface that already carries an
  api-catalog, an agent card, an MCP server card, an ai-catalog and a skills
  index.
