SCA: security update for pyload-ng (GHSA-mvwx-582f-56r7)

medium Tenable Cloud Security Plugin ID 440009

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev97, the
_safe_extractall() function in src/pyload/plugins/extractors/UnTar.py uses os.path.commonprefix() for its
path traversal check, which performs character-level string comparison rather than path-level comparison.
This allows a specially crafted tar archive to write files outside the intended extraction directory. The
correct function os.path.commonpath() was added to the codebase in the CVE-2026-32808 fix (commit 5f4f0fa)
but was never applied to _safe_extractall(), making this an incomplete fix. This vulnerability is fixed in
0.5.0b3.dev97. (CVE-2026-35592)

Solution

Update the pyload-ng library and its related packages to version 0.5.0b3.dev97 or later.
