CVE-2026-41272

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the core security wrappers (secureAxiosRequest and secureFetch) intended to prevent Server-Side Request Forgery (SSRF) contain multiple logic flaws. These flaws allow attackers to bypass the allow/deny lists via DNS Rebinding (Time-of-Check Time-of-Use) or by exploiting the default configuration which fails to enforce any deny list. 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 3.1.0, los envoltorios de seguridad principales (secureAxiosRequest y secureFetch) destinados a prevenir la Falsificación de Petición del Lado del Servidor (SSRF) contienen múltiples fallos lógicos. Estos fallos permiten a los atacantes eludir las listas de permitidos/denegados mediante Rebinding de DNS (Tiempo de Verificación Tiempo de Uso) o explotando la configuración predeterminada que no logra aplicar ninguna lista de denegados. Esta vulnerabilidad está corregida en 3.1.0.
