CVE-2021-28861 Open this link in a new tabHow to fix?
Upgrade AlmaLinux:9 python3-libs to version 0:3.9.14-1.el9 or higher.
This issue was patched in ALSA-2022:8353.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-libs package and not the python3-libs package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks."
