Short explanation
In virtualenv prior to version 21.14.9, caller-supplied prompt text can become executable syntax in the bash activation prompt. An attacker must influence the value passed to virtualenv, and a user must subsequently activate the environment and draw the prompt.
This vulnerability carries high risks that can lead to severe confidentiality, integrity, and availability impacts in affected environments. Since the patch status remains unknown, following vendor advisories is recommended.
What should be done?
- Follow vendor advisories.
- Apply updates where available.
- Review environment configurations.
