CVE-2026-67429

Full vulnerability record from the local CVENow database.

Description

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.

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."
