CVE-2026-56275

Flowise before 3.1.0 contains a server-side request forgery vulnerability in the Execute Flow node that allows attackers to bypass security validation by providing intranet addresses through the base URL field. Attackers can initiate HTTP requests to internal network addresses, access cloud metadata, and enumerate internal services by exploiting the missing secureFetch verification in httpSecurity.ts.

Summary		(es) Flowise antes de la versión 3.1.0 contiene una vulnerabilidad de falsificación de petición del lado del servidor en el nodo Execute Flow que permite a los atacantes eludir la validación de seguridad al proporcionar direcciones de intranet a través del campo base URL. Los atacantes pueden iniciar peticiones HTTP a direcciones de red internas, acceder a metadatos de la nube y enumerar servicios internos al explotar la verificación secureFetch faltante en httpSecurity.ts.
