Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows
HTTP Response Splitting. If a program using WEBrick inserts untrusted input
into the response header, an attacker can exploit it to insert a newline
character to split a header, and inject malicious content to deceive
clients. NOTE: this issue exists because of an incomplete fix for
CVE-2017-17742, which addressed the CRLF vector, but did not address an
isolated CR or an isolated LF.
