CVE-2026-41270

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, a Server-Side Request Forgery (SSRF) protection bypass vulnerability exists in the Custom Function feature. While the application implements SSRF protection via HTTP_DENY_LIST for axios and node-fetch libraries, the built-in Node.js http, https, and net modules are allowed in the NodeVM sandbox without equivalent protection. This allows authenticated users to bypass SSRF controls and access internal network resources (e.g., cloud provider metadata services) This vulnerability is fixed in 3.1.0.

Summary		(es) Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo de modelo de lenguaje grande personalizado. Antes de la versión 3.1.0, existe una vulnerabilidad de omisión de protección de falsificación de petición del lado del servidor (SSRF) en la característica de Función Personalizada. Si bien la aplicación implementa protección SSRF a través de HTTP_DENY_LIST para las bibliotecas axios y node-fetch, los módulos integrados de Node.js http, https y net están permitidos en la sandbox NodeVM sin protección equivalente. Esto permite a los usuarios autenticados omitir los controles SSRF y acceder a recursos de red internos (por ejemplo, servicios de metadatos de proveedores de la nube). Esta vulnerabilidad está corregida en la versión 3.1.0.
