virtualenv 21.14.13 includes fixes to prevent shell-command execution through crafted prompts and to prevent redirected writes via planted links.
21.14.13 Bugfixes - 21.14.13 Stop bash running commands from --prompt or an environment name containing $(...), backticks or a backslash after shopt -s promptvars, set -o posix, or in a child shell that inherits an exported PS1 (GHSA-cx6f-vjhg-g3cc); reported by rozzkml. zsh now draws the prompt from psvar[9], which is never parsed as shell syntax. Write the .venv redirect and the wheel RECORD with exclusive create, so a link planted after the existence check cannot redirect the write.
