How to fix?

Upgrade Centos:7 python-libs to version 0:2.7.5-92.el7_9 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-libs package and not the python-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this is similar to CVE-2020-26116.
