Leandata Vulnerability Disclosure

description: >-
  LeanData publishes a Responsible Disclosure program on its SafeBase trust center, listed as
  an enabled control with full maturity and a HackerOne integration flag set. That is a real,
  provider-published disclosure posture — but it is reachable only as an item inside a
  JavaScript-rendered trust portal. There is no RFC 9116 security.txt on any LeanData host, no
  standalone /responsible-disclosure page, and no published security@ contact address, so an
  automated scanner or an agent looking for where to report a vulnerability will find nothing.
  The program exists; its discovery surface does not.

  note: >-
    The trust center's control record carries integrations.hackerone.allowed = true. LeanData
    does not publish a public HackerOne program URL and none was found, so this is recorded as
    an advertised integration capability, not a confirmed public bounty program.
