description: >-
  Tapcart runs a published vulnerability disclosure program with a
  machine-readable RFC 9116 security.txt and stated triage SLAs. Note the
  discovery problem: neither the security.txt nor the policy page lives on
  tapcart.com. Both are served from security.tapcart.com — a Google Cloud
  Storage bucket named tapcart-vulnerability-program behind Cloudflare — and
  https://www.tapcart.com/.well-known/security.txt returns 404. A researcher or
  scanner following RFC 9116 against the primary domain will not find this
  program.
policy:
  - https://security.tapcart.com/vulnerability-program.html
  - https://security.tapcart.com/.well-known/security.txt

bug_bounty:
  present: false
  note: >-
    No paid bounty and no HackerOne / Bugcrowd / Intigriti program was found.
    This is a coordinated disclosure program only.

  url: https://security.tapcart.com/.well-known/security.txt

  fields:
    Contact: mailto:security@tapcart.co

    Policy: https://security.tapcart.com/.well-known/security.txt
    Preferred-Languages: en
  deviations:
    - >-
      The Policy field points back at security.txt itself rather than at the
      human-readable policy page (vulnerability-program.html), so an automated
      consumer following Policy gets the same file it already has.
    - >-
      Expires is set ~10 years out. RFC 9116 recommends less than a year so the
      file is demonstrably maintained.
    - No Encryption, Acknowledgments, Canonical, or Hiring fields.
