Fannie Mae Vulnerability Disclosure

note: >-
  Fannie Mae runs a first-party vulnerability disclosure channel — a published policy page and an
  intake form on its own domain. It does NOT run a bug bounty. The hackerone.com/fanniemae page that
  turns up in search is HackerOne's community-curated, explicitly UNCLAIMED directory entry (the page
  carries class "spec-external-unclaimed" and describes itself as "community-curated"); it is
  recorded here as a third-party listing, not as a Fannie Mae program.

    /.well-known/security.txt returns 404 on www.fanniemae.com, fanniemae.com and
    fmsso.fanniemae.com. The disclosure channel exists but is not machine-discoverable — publishing
    an RFC 9116 security.txt pointing at the existing form would close this with no new process.

    CAA iodef record on fanniemae.com — 128 iodef "mailto: iso_support@fanniemae.com" (see

  cybersecurity_requirements_note: >-
    Requirements Fannie Mae imposes on its sellers, servicers and technology partners (including a
    36-hour cybersecurity incident notification obligation) — an obligation Fannie Mae places on
    others, not a certification Fannie Mae holds. It is deliberately NOT recorded as a trust center
    or compliance attestation.
trust_center:
  exists: false
  note: >-
    No trust center, no published SOC 2 / ISO 27001 / PCI / FedRAMP attestation, and no compliance
    portal was found on any fanniemae.com host (probe-security-programs.py 2026-09-07 returned
    vdp=none trust=none; this file is the manual upgrade of its vdp result). Fannie Mae is a
    government-sponsored enterprise supervised by FHFA; its published governance material is
    regulatory, not a customer-facing certification set.
