CVE-2020-26137  (opens in a new tab)
CWE-74  (opens in a new tab)

How to fix?

Upgrade SLES:15.1 python2-urllib3 to version 1.25.10-9.14.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-urllib3 package and not the python2-urllib3 package as distributed by SLES. See How to fix? for SLES:15.1 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.
