CVE-2026-62388: Python Lexical Traversal Check Without Resolution
Lexical path checks (such as checking for '..' or os.path.isabs) do not prevent symlink-based path traversal. Validate that the resolved target path is strictly contained within the expected root directory using Path.resolve() and is_relative_to or os.path.commonpath.
