Possible to hijack modules in current working directory (CVE-2026-5271)

Summary

Possible to hijack modules in current working directory

Original description

The description as published by the source.

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.
