On Python < 3.11 on Windows, os.path.isabs()
does not catch UNC paths like //server/share
. Werkzeug's safe_join()
relies on this check, and so can produce a path that is not safe, potentially allowing unintended access to data. Applications using Python >= 3.11, or not using Windows, are not vulnerable.
