CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
cgi.rb in Ruby through 2.6.x, through 3.0x, and through 3.1.x allows HTTP
header injection. If a CGI application using the CGI library inserts
untrusted input into the HTTP response header, an attacker can exploit it to
insert a newline character to split a header, and inject malicious content to
deceive clients.
