Upstart Vulnerability Disclosure

Vulnerability disclosure

Upstart publishes an RFC 9116 security.txt at https://www.upstart.com/.well-known/security.txt (served on both www.upstart.com and api.upstart.com; Canonical points at www). It directs reports to a vulnerability-reporting page under the lender regulatory-compliance section and documents a private bug bounty program reachable by emailing security@upstart.com for an invite. Note: the security.txt Expires field (2025-09-01) is in the past - the file is stale per RFC 9116 but still served.

Upstart publishes a vulnerability disclosure policy for reporting security issues. A machine-readable /.well-known/security.txt is served. A dedicated security contact is published.
