CVE-2025-68478

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.7.0, if an arbitrary path is specified in the request body's `fs_path`, the server serializes the Flow object into JSON and creates/overwrites a file at that path. There is no path restriction, normalization, or allowed directory enforcement, so absolute paths (e.g., /etc/poc.txt) are interpreted as is. Version 1.7.0 fixes the issue.

Summary		(es) Langflow es una herramienta para construir y desplegar agentes y flujos de trabajo impulsados por IA. Antes de la versión 1.7.0, si se especifica una ruta arbitraria en el 'fs_path' del cuerpo de la solicitud, el servidor serializa el objeto Flow a JSON y crea/sobrescribe un archivo en esa ruta. No hay restricción de ruta, normalización o aplicación de directorio permitido, por lo que las rutas absolutas (p. ej., /etc/PoC.txt) se interpretan tal cual. La versión 1.7.0 corrige el problema.
