      "value": "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."

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."
