SCA: security update for virtualenv (GHSA-cx6f-vjhg-g3cc)

high Tenable Self-Hosted Container Security Plugin ID 477251

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. From 21.14.9 until 21.14.13, the
 bash bin/activate script can copy an attacker-controlled --prompt value into PS1 without escaping dollar
 signs or backticks when both promptvars and POSIX mode are disabled during activation. Re-enabling
 promptvars, running set -o posix, or starting an interactive child bash that inherits the exported PS1 can
 then expand command substitution in the stored VIRTUAL_ENV_PROMPT value and execute commands as the user
 who activates the environment. This issue is fixed in version 21.14.13. (CVE-2026-115586)

Solution

Update the virtualenv library and its related packages to version 21.14.13 or later.
