CVE-2026-34207

TypeBot is a chatbot builder tool. In versions prior to 3.16.0, SSRF protection for Webhook / HTTP Request blocks validates only the URL string, blocked hostname literals, and literal IP formats. It does not resolve DNS before allowing the request. As a result, a hostname such as ssrf-repro.example that resolves to 127.0.0.1, 169.254.169.254, or RFC1918/private space passes validation and is later fetched by the backend HTTP client. This enables server-side request forgery to loopback, cloud metadata, and private network targets. This issue has been resolved in version 3.16.0.

Summary		(es) TypeBot es una herramienta de creación de chatbots. En versiones anteriores a la 3.16.0, la protección SSRF para los bloques de Webhook / Petición HTTP valida solo la cadena de URL, los literales de nombre de host bloqueados y los formatos de IP literales. No resuelve DNS antes de permitir la petición. Como resultado, un nombre de host como ssrf-repro.example que se resuelve a 127.0.0.1, 169.254.169.254 o espacio RFC1918/privado pasa la validación y es posteriormente obtenido por el cliente HTTP del backend. Esto permite la falsificación de petición del lado del servidor a objetivos de bucle invertido, metadatos de la nube y redes privadas. Este problema ha sido resuelto en la versión 3.16.0.
