CVE-2026-67429

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.6, image.download and related file-writing modules use caller-controlled output_dir instead of validate_path_with_env_config and its FLYTO_SANDBOX_DIR confinement, allowing attacker-controlled response bytes to be written to arbitrary filesystem paths the process can access. This issue is fixed in version 2.26.6.

Summary		(es) Flyto2 Core es un kernel de ejecución para flujos de trabajo de automatización y agentes de IA. Antes de la versión 2.26.6, image.download y los módulos relacionados de escritura de archivos utilizan un output_dir controlado por el llamador en lugar de validate_path_with_env_config y su confinamiento FLYTO_SANDBOX_DIR, lo que permite que bytes de respuesta controlados por el atacante se escriban en rutas arbitrarias del sistema de archivos a las que el proceso puede acceder. Este problema está solucionado en la versión 2.26.6.
