CWE-22  (opens in a new tab)

How to fix?

Upgrade Debian:unstable python-pip to version 20.0.2-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-pip package and not the python-pip package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The pip package before 19.2 for Python allows Directory Traversal when a URL is given in an install command, because a Content-Disposition header can have ../ in a filename, as demonstrated by overwriting the /root/.ssh/authorized_keys file. This occurs in _download_http_url in _internal/download.py.
