NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-lxml package and not the python3-lxml package as distributed by Rocky-Linux.
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.
