CVE-2026-67429 Details
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.
A vulnerability in Flyto2 Core versions prior to 2.26.6 allows for arbitrary file writes via the image.download module. The issue arises because the module uses a caller-controlled output directory without proper validation, enabling attacker-controlled response bytes to be written to any accessible filesystem path. This vulnerability is part of a broader issue affecting several file-writing modules within the application.
Users are advised to upgrade to Flyto2 Core version 2.26.6, where this vulnerability has been fixed.
