How to fix?

Upgrade RHEL:8 python3-idle to version 0:3.6.8-48.el8_7.1 or higher.
This issue was patched in RHSA-2023:0833.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-idle package and not the python3-idle package as distributed by RHEL. See How to fix? for RHEL:8 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."
