      "value": "AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to 0.6.52, an authenticated user can bypass the SSRF / private-IP protections in SendWebRequestBlock and reach internal network services. _is_ip_blocked() in backend/backend/util/request.py does not normalize IPv4-mapped IPv6 addresses before checking resolved IPs against the blocked IPv4 ranges, and does not block special-use ranges such as 100.64.0.0/10 (CGNAT, RFC 6598). A hostname that resolves to an IPv4-mapped IPv6 address therefore passes validation and the request reaches the embedded internal IPv4 endpoint. This affects all AutoGPT Platform deployments. This vulnerability is fixed in 0.6.52."

      "value": "AutoGPT es una plataforma de automatización de flujos de trabajo para crear, desplegar y gestionar agentes de inteligencia artificial continuos. Antes de la versión 0.6.52, un usuario autenticado puede eludir las protecciones de SSRF / IP privada en SendWebRequestBlock y alcanzar servicios de red internos. _is_ip_blocked() en backend/backend/util/request.py no normaliza las direcciones IPv6 mapeadas a IPv4 antes de comprobar las IPs resueltas contra los rangos de IPv4 bloqueados, y no bloquea rangos de uso especial como 100.64.0.0/10 (CGNAT, RFC 6598). Un nombre de host que se resuelve en una dirección IPv6 mapeada a IPv4, por lo tanto, pasa la validación y la solicitud alcanza el punto final IPv4 interno incrustado. Esto afecta a todas las implementaciones de la Plataforma AutoGPT. Esta vulnerabilidad está corregida en la versión 0.6.52."
