SCA: security update for virtualenv (GHSA-cx28-75q4-x26q)

low Tenable Cloud Security Plugin ID 477207

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,
 PipInvoke.get_pip_install_cmd() handles --seeder pip --download by calling get_wheel(download=False) and
 then allowing pip to consult the configured index, bypassing virtualenv's download_wheel() and
 verify_wheel_digest() path. When virtualenv's default-index PyPI digest comparison remains enabled, an
 index candidate matching the bundled package and version can therefore be selected without comparison to
 PyPI SHA-256 metadata. Explicit custom-index settings already opt out of that comparison and remain
 outside this verification-bypass claim; the demonstrated configuration used a non-PyPI index while leaving
 the index environment variables unset so the comparison policy remained active. This condition does not
 independently defeat TLS or establish control of the index response. This issue is fixed in version
 21.14.9. (CVE-2026-113717)

Solution

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