CVE-2026-57573

Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server applied its SSRF destination check on the non-streaming /crawl path but not on the streaming path. handle_stream_crawl_request passed seed URLs straight to the crawler with no destination validation, allowing a remote unauthenticated client to call POST /crawl/stream or POST /crawl with crawler_config.stream=true with a URL pointing at an internal, private, or link-local address; the server fetched it and streamed the response body back. This issue is fixed in version 0.9.0.

Summary		(es) Crawl4AI es un rastreador y raspador web de código abierto compatible con LLM. Antes de 0.9.0, el servidor API de Docker aplicaba su verificación de destino SSRF en la ruta /crawl no de transmisión, pero no en la ruta de transmisión. handle_stream_crawl_request pasaba las URL semilla directamente al rastreador sin validación de destino, permitiendo a un cliente remoto no autenticado llamar a POST /crawl/stream o POST /crawl con crawler_config.stream=true con una URL apuntando a una dirección interna, privada o de enlace local; el servidor la recuperaba y transmitía el cuerpo de la respuesta de vuelta. Este problema se ha corregido en la versión 0.9.0.
