NVD Description
Note: Versions mentioned in the description apply only to the upstream python-twisted-web package and not the python-twisted-web package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In Twisted before 19.2.1, twisted.web did not validate or sanitize URIs or HTTP methods, allowing an attacker to inject invalid characters such as CRLF.
