      "value": "Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, an improper mass assignment (JSON injection) vulnerability in the account registration endpoint of Flowise Cloud allows unauthenticated attackers to inject server-managed fields and nested objects during account creation. This enables client-controlled manipulation of ownership metadata, timestamps, organization association, and role mappings, breaking trust boundaries in a multi-tenant environment. This vulnerability is fixed in 3.1.0."

      "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, una vulnerabilidad de asignación masiva incorrecta (inyección JSON) en el endpoint de registro de cuentas de Flowise Cloud permite a atacantes no autenticados inyectar campos gestionados por el servidor y objetos anidados durante la creación de la cuenta. Esto permite la manipulación controlada por el cliente de metadatos de propiedad, marcas de tiempo, asociación de organización y mapeos de roles, rompiendo los límites de confianza en un entorno multi-inquilino. Esta vulnerabilidad está corregida en la versión 3.1.0."
