Prior to 3.1.0, Flowise is vulnerable to a critical unauthenticated remote command execution (RCE) vulnerability. It can be exploited via a parameter override bypass using the FILE-STORAGE:: keyword combined with a NODE_OPTIONS environment variable injection. This allows for the execution of arbitrary system commands with root privileges within the containerized Flowise instance, requiring only a single HTTP request and no authentication or knowledge of the instance. This vulnerability is fixed in 3.1.0."},{"lang":"es","value":"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, Flowise es vulnerable a una crítica vulnerabilidad de ejecución remota de comandos (RCE) no autenticada. Puede ser explotada a través de un bypass de anulación de parámetros utilizando la palabra clave FILE-STORAGE:: combinado con una inyección de variable de entorno NODE_OPTIONS. Esto permite la ejecución de comandos de sistema arbitrarios con privilegios de root dentro de la instancia de Flowise en contenedores, requiriendo solo una única solicitud HTTP y sin autenticación ni conocimiento de la instancia.
