CVE-2026-108602
Helicone hasta la versión v2025.08.21-1 contiene una vulnerabilidad de falsificación de solicitudes del lado del servidor en el remitente de webhooks Jawn que permite a usuarios autenticados de la organización alcanzar servicios internos utilizando nombres de host que se resuelven en direcciones privadas. Los atacantes pueden crear webhooks con nombres de host públicos que se resuelvan o realicen DNS rebinding a direcciones de bucle local o internas, causando solicitudes POST ciegas a servicios HTTPS internos.
