From 68c170e79c1085053e8f78e3e79d6cb9882eb066 Mon Sep 17 00:00:00 2001 From: Tommaso Bona Date: Sat, 30 Aug 2025 12:27:32 +0200 Subject: [PATCH] gh-138158: Use the `"data"` tarfile extraction filter in `Tools/ssl/multissltests.py` (GH-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.
