      "value": "PraisonAI is a multi-agent teams system. In versions prior to 1.6.58, the web_crawl tool performs its SSRF check only on the initially supplied URL, allowing the protection to be bypassed so the tool connects to attacker-chosen internal destinations. The check resolves the hostname once with socket.gethostbyname and rejects private/loopback/link-local results, but then passes the URL to a fetcher using httpx.Client(follow_redirects=True) (or urllib.request.urlopen when httpx is absent, which also follows redirects) that re-resolves the hostname at connect time with no further validation. This validate-here/fetch-there gap is exploitable through both HTTP redirects and DNS rebinding. If an attacker can influence URLs passed to web_crawl(), directly or through an agent/tool workflow, they can cause the PraisonAI host to fetch loopback, private-network, or cloud metadata endpoints reachable from that host, with the response body returned in the web_crawl() result. This issue has been fixed in version 1.6.58."

      "value": "PraisonAI es un sistema de equipos multiagente. En versiones anteriores a la 1.6.58, la herramienta web_crawl realiza su verificación de SSRF solo en la URL suministrada inicialmente, permitiendo que la protección sea eludida para que la herramienta se conecte a destinos internos elegidos por el atacante. La verificación resuelve el nombre de host una vez con socket.gethostbyname y rechaza resultados privados/loopback/link-local, pero luego pasa la URL a un ’fetcher’ usando httpx.Client(follow_redirects=True) (o urllib.request.urlopen cuando httpx está ausente, que también sigue redirecciones) que vuelve a resolver el nombre de host en el momento de la conexión sin validación adicional. Esta brecha de validar aquí/obtener allá es explotable a través de redirecciones HTTP y DNS rebinding. Si un atacante puede influir en las URL pasadas a web_crawl(), directamente o a través de un flujo de trabajo de agente/herramienta, pueden hacer que el host de PraisonAI obtenga puntos finales de loopback, de red privada o de metadatos de la nube accesibles desde ese host, con el cuerpo de la respuesta devuelto en el resultado de web_crawl(). Este problema ha sido solucionado en la versión 1.6.58."
