Sorry, something went wrong.
…/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.

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.
