Lack of data validation - Path Traversal In werkzeug
Description
Werkzeug safe_join not safe on Windows
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.
Mitigation
Update Impact
