generated: '2026-08-27' method: probed source: >- Direct unauthenticated GET of each /.well-known/ path on every host named in apis.yml — the marketing/docs host www.elastic.co and the Elastic Cloud control-plane host api.elastic-cloud.com (the baseURL of the Elastic Cloud API). The Elasticsearch and Kibana base URLs are customer-deployment specific, so they have no shared host to probe. note: >- One real document was served: api.elastic-cloud.com/.well-known/security.txt returns text/plain RFC 9116 content naming security@elastic.co, an OpenPGP fingerprint and a disclosure policy URL. Saved verbatim as elk-stack-security.txt. Every other path either 404s or returns the Elastic Cloud single-page-app shell — api-catalog and oauth-authorization-server both answer HTTP 200 with an identical 9,582-byte text/html document, which is an SPA catch-all and NOT a served document; both are recorded as misses. hosts: - host: api.elastic-cloud.com documents: - path: /.well-known/security.txt status: 200 content_type: text/plain; charset=UTF-8 file: elk-stack-security.txt - path: /.well-known/openid-configuration status: 200 content_type: text/html; charset=utf-8 note: SPA shell (9,582 bytes of HTML), not an OpenID discovery document — treated as a miss - path: /.well-known/oauth-authorization-server status: 200 content_type: text/html; charset=utf-8 note: SPA shell (9,582 bytes of HTML), identical body to /.well-known/api-catalog — treated as a miss - path: /.well-known/api-catalog status: 200 content_type: text/html; charset=utf-8 note: SPA shell (9,582 bytes of HTML), not an RFC 9727 catalog — treated as a miss - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: www.elastic.co documents: - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/oauth-authorization-server status: 404 - path: /.well-known/api-catalog status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 - host: elastic.co documents: - path: /.well-known/security.txt status: 404
