Overview

Affected versions of this package are vulnerable to Unquoted Search Path or Element due to improper quoting of path names during the creation of virtual environments. An attacker can execute arbitrary commands when the virtual environment is activated by injecting commands into the activation scripts.

Note:

Virtual environments which are not created by an attacker or which aren't activated before being used (ie ./venv/bin/python) are not affected.

PoC

envname='";uname -a;"'
mkdir "$envname"
cd "$envname"
python3 -m venv .
. ./bin/activate
