How to fix?

Upgrade Debian:11 pypy3 to version 7.3.5+dfsg-2+deb11u4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pypy3 package and not the pypy3 package as distributed by Debian. See How to fix? for Debian:11 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."
