pymanager included the current working directory in sys.path meaning modules could be shadowed by modules in the current working directory. As a result, if a user executes a pymanager-generated command (e.g., pip, pytest)
from an attacker-controlled directory, a malicious module in that
directory can be imported and executed instead of the intended package.
