SCA: security update for virtualenv (GHSA-fc2g-4w5p-6whm)

medium Tenable Cloud Security Plugin ID 477216

Description

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

- virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the app-data
copy seeder uses shutil.copy() to copy cached package files into later environments, causing cached source
modes to override the current run's umask. A cache populated under a permissive umask can therefore
produce files writable by another local account in a later traversable environment, allowing package code
such as pip/__init__.py to be modified and executed by the environment owner. The attacker cannot force
the earlier umask, and a private destination parent prevents access. This issue is fixed in version
21.14.9. (CVE-2026-113720)

Solution

Update the virtualenv library and its related packages to version 21.14.9 or later.
