      "value": "Typebot is a chatbot builder tool. In versions 3.15.2 and prior, the preview chat endpoint (POST /api/v1/typebots/{typebotId}/preview/startChat) allows unauthenticated users to achieve Server-Side Request Forgery (SSRF) by supplying a custom typebot definition with server-side code blocks. The fetch function exposed inside the isolated-vm sandbox calls Node.js native fetch without the SSRF validation (validateHttpReqUrl) that protects the HTTP Request block. This bypasses all SSRF mitigations added after GHSA-8gq9-rw7v-3jpr. Exploitation of this unauthenticated SSRF vulnerability can lead to cloud credential theft, internal network access and data exfiltration for any self-hosted Typebot deployments and hosted services. This issue has been fixed in version 3.16.0."

      "value": "Typebot es una herramienta de creación de chatbots. En las versiones 3.15.2 y anteriores, el endpoint de previsualización de chat (POST /api/v1/typebots/{typebotId}/preview/startChat) permite a usuarios no autenticados lograr Falsificación de Petición del Lado del Servidor (SSRF) al proporcionar una definición de typebot personalizada con bloques de código del lado del servidor. La función fetch expuesta dentro del sandbox isolated-vm llama a la función fetch nativa de Node.js sin la validación de SSRF (validateHttpReqUrl) que protege el bloque de Petición HTTP. Esto elude todas las mitigaciones de SSRF añadidas después de GHSA-8gq9-rw7v-3jpr. La explotación de esta vulnerabilidad de SSRF no autenticada puede conducir al robo de credenciales en la nube, acceso a la red interna y exfiltración de datos para cualquier despliegue de Typebot autoalojado y servicios alojados. Este problema ha sido solucionado en la versión 3.16.0."
