…/ssl/multissltests.py` (pythonGH-138147) The `Tools/ssl/multissltests.py` script may extract a possibly untrusted tarball. Since the script does not necessarily use Python 3.14 or later (where the `"data"` filter became the default `tarfile` extraction filter), the user may theoretically suffer from a path traversal attack. Although the script should not be used in production and usually relies on downloading trusted sources, the `"data"` extraction filter is now explicitly used wherever relevant.
