SCA: security update for virtualenv (GHSA-394h-qwmc-48pf)

high Tenable Self-Hosted Container Security Plugin ID 477209

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, POSIX xonsh
 activation quote() uses repr() to write printable non-ASCII prompt or destination data into UTF-8
 activate.xsh, while xonsh can read that script using $XONSH_ENCODING. Under a legacy multibyte codec such
 as GBK or Big5, a UTF-8 trail byte can consume the backslash before an adjacent quote, allowing the
 literal to close and attacker-influenced statements to execute when the user sources the generated script.
 This issue is fixed in version 21.14.9. (CVE-2026-113718)

Solution

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