Waystar Vulnerability Disclosure

Vulnerability disclosure

Waystar publishes a responsible-disclosure page on its main website naming a security contact. It is a minimal policy - a contact address and a statement of intent. There is no bug bounty, no safe-harbor language, no scope definition, no PGP key, no structured reporting form, and no RFC 9116 /.well-known/security.txt on any Waystar or ZirMed host (every host probed returned 404 - see well-known/waystar-well-known.yml). A researcher has an address to write to and nothing else.

Waystar runs a coordinated vulnerability disclosure program on Hackerone. A machine-readable /.well-known/security.txt is served. A dedicated security contact is published.
