Because the routing algorithm relies on the raw HTTP path while `request.url` is rebuilt from the `Host` header, a malformed header could make `request.url.path` differ from the path that was actually requested. Middleware and endpoints that apply security restrictions based on `request.url` (rather than the raw `scope` path) could therefore be bypassed.\n\n### Details\nWhen a client requests `http://example.com/foo`, it sends:\n\n```http\nGET /foo HTTP/1.1\nHost: example.com\n```\n\nAffected versions reconstructed the URL by concatenating `http://{host}{path}` and re-parsing the result. The `Host` value is only valid as a `uri-host [ \":\" port ]` per RFC 9112 §3.2, where `uri-host` follows the restricted `host` grammar of RFC 3986 §3.2.2. When it contains characters outside that grammar - notably `/`, `?`, or `#` - those characters move the path/query/fragment boundaries during re-parsing, so the parsed `request.url.path` no longer matches the","public_affected_ranges":["<= 1.0.0"]},{"certainty":"source_listed","source_ids":["sr-a87a914fea83e1a4b93c9ec47fbff664"],"technology":"Kludex Starlette","known_exclusions":[],"conditions_summary":"CISA does not supply a complete application-specific affected range here.
