| Описание | The FileResolver is designed with security configuration options (allowed_hosts, allowed_mime_types, magic-byte verification, size and concurrency limits). However, allowed_hosts=None is the default, and in that mode the resolver performs an httpx GET on any http(s) URL supplied via the client-controlled fileId (or an LLM-initiated tool call), following redirects. The redirect-host check only runs when an allowlist is configured, and the connection is already made before any check — leaving a blind-request window and a DNS-rebinding TOCTOU (validation and connection resolve the hostname independently). |
