NVD Description

Note: Versions mentioned in the description apply only to the upstream twisted package and not the twisted package as distributed by Echo. See How to fix? for Echo:latest 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.
