NVD Description

Note: Versions mentioned in the description apply only to the upstream python27:2.7/python2-pip-wheel package and not the python27:2.7/python2-pip-wheel package as distributed by RHEL. See How to fix? for RHEL:8 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.
