 | user_url_validation | boolean | Default `true`. When `true`, the proxy validates user-controlled URLs (e.g. OpenAPI `spec_path` when it is an `http(s)` URL, image URLs, and similar) before fetching: DNS is resolved and connections to non–globally-routable addresses (RFC1918, loopback, link-local, etc.) are blocked unless the **hostname in the URL** is listed in `user_url_allowed_hosts`. Set to `false` to skip validation (only if you trust who can supply URLs). **Must be set under `litellm_settings`**, not `general_settings`. |
 | user_url_allowed_hosts | array of strings | Hostnames allowed to resolve to private/internal IPs when `user_url_validation` is `true`. Match the host **as it appears in the URL** (e.g. `api.corp.internal`, `127.0.0.1`, `127.0.0.1:8080`, `[::1]:443`). For split-horizon DNS, allowlist the public hostname, not the resolved `10.x` address. **Must be set under `litellm_settings`**, not `general_settings`. See [MCP from OpenAPI](../mcp_openapi#internal-spec-urls-ssrf). |

+By default, `POST /v1/files` falls back to the classic provider file path when `target_model_names` is omitted. Set `require_managed_files: true` under `litellm_settings` to require managed files on every upload.
