CVE-2026-46402: Path traversal vulnerability

Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO uses the user-controlled task_name value directly when constructing session log paths. An authenticated client can supply path traversal sequences in task_name and cause UFO to create log directories and log files outside the intended logs/ directory.
