SCA: security update for virtualenv (GHSA-8rjx-v5ww-45pp)
high Tenable Cloud Security Plugin ID 476565
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 20.26.6 until 21.14.2,
ViaTemplateActivator.instantiate_template() replaces placeholders one key at a time across the complete
activation template, so trigger names such as __VIRTUAL_NAME__, __VIRTUAL_ENV__, or __VIRTUAL_PROMPT__
inside an already substituted and quoted environment path or prompt can be replaced during a later pass.
The later value's quoting can close the earlier literal and execute the remaining path when a user
activates the environment through bash, fish, xonsh, or activate_this.py. The distinct csh prompt-display
token __VIRTUAL_PROMPT_DISPLAY_TCSH__ can instead break the generated script without establishing command
execution. The attacker must influence the destination path or --prompt, and a value without a relevant
placeholder name does not trigger this mechanism. This issue is fixed in version 21.14.2.
(CVE-2026-113776)
Solution
Update the virtualenv library and its related packages to version 21.14.2 or later.See Also
