Echo: virtualenv: security update to 21.7.12

high Tenable Cloud Security Plugin ID 471103

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 21.7.12,
 BatchActivator.quote() returns prompt text unchanged before activate.bat inserts it into a cmd.exe set
 "VAR=value" statement. An attacker who influences --prompt, VIRTUALENV_PROMPT, or the corresponding
 configuration value can include a double quote that closes the assignment and leaves following cmd.exe
 operators as executable syntax. When a user activates the generated Windows environment, the injected
 commands run with that user's privileges. This issue is fixed in version 21.7.12. (CVE-2026-102937)

Solution

Update the virtualenv library and its related packages to version 21.7.12 or later.
