# serves no /.well-known/security.txt on any host in this record (probed
# 2026-09-05 — see well-known/comcast-well-known.yml). The program nevertheless
# exists and is substantial; it is simply not discoverable at the RFC 9116 path.
# Upgraded to method: searched from the provider's own published policy page.

  www.xfinity.com, developers.xfinity.com, docs.developer.comcast.com,
  developer.comcast.com or either codebig2.net API host. This is a real
  discoverability gap: a machine looking for the program at the standard path
  will not find it, and www.comcast.com additionally answers 406 to crawlers.

    "not all submissions are eligible for a reward; eligibility depends on the
    merit, quality, and impact of the findings."
scope_definition: >-
  Comcast defines a security vulnerability as "an unintended weakness or
  exposure that could be used to compromise the integrity, availability or
  confidentiality of our products and services." Reports are accepted from
  independent researchers, industry partners, vendors, customers and
  consultants.
principles:
  - Trust — confidentiality is maintained in exchanges with researchers.
  - Respect — researchers are asked to avoid privacy violations, degradation of user experience, disruption of production systems and destruction of data.
  - Transparency — researchers provide the technical detail needed to validate a report.
  - Common Good — no public disclosure of unverified vulnerabilities before validation.

  The policy is written for Comcast/Xfinity products and services generally. It
  does not name the Firebolt developer platform, docs.developer.comcast.com or
  the codebig2.net API hosts in scope, and the Bugcrowd scopes were not readable
  anonymously. No claim is made either way.
