Two real findings from the security reviewer: 1. urllib auto-follows 3xx redirects via the default HTTPRedirectHandler. The previous code's hop loop never ran — urllib silently followed. Replaced with http.client + a manual hop loop. Every hop re-runs _validate_url, so an open-redirect to 127.0.0.1 / RFC1918 / metadata gets caught on the second hop. 2. DNS TOCTOU — _resolve() validated but urllib.request re-resolved on connect. Now the connection is pinned to the validated IP via a PinnedHTTPConn / PinnedHTTPSConn subclass that overrides connect() to bind socket.create_connection to (addr, port). For HTTPS, TLS server_hostname is set to the original host so SNI + cert verification still work against the named host while the TCP destination is the pinned IP. Tests added: redirect-to-loopback short-circuits at validation; too-many-redirects exhausts max_hops; 2xx returns body; non-2xx raises. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
