An unauthenticated remote attacker can exhaust server memory, disk space, and CPU by pointing the endpoint at an infinite-streaming HTTP server or a long high-framerate video, causing a complete denial of service. No credentials or special configuration are required; the route is open by default.\n\n### Details\nThree independent sinks contribute to the vulnerability:\n\n**1. Unbounded image/audio fetch (`mistralrs-server-core/src/util.rs:59–62`)**\n\n```rust\nlet bytes = if url.scheme() == \"http\" || url.scheme() == \"https\" {\n    match reqwest::get(url.clone()).await {\n        Ok(http_resp) => http_resp.bytes().await?.to_vec(), // no byte cap\n        Err(e) => anyhow::bail!(e),\n    }\n```\n\n`bytes().await` buffers the entire HTTP response body before returning. There is no `Content-Length` check, no streaming limit, and no timeout specific to the media fetch.
