CVE-2019-20916 (GCVE-0-2019-20916)

Vulnerability from cvelistv5

Published

Modified

2024-08-05 03:00

Severity ?

CWE

Summary

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.
