|Importance||--- / normal|
An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6,
and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with
Ruby, had not checked the transfer-encoding header value rigorously.
An attacker may potentially exploit this issue to bypass a reverse
proxy (which also has a poor header check), which may lead to an HTTP
Request Smuggling attack.
Fixed in >= webrick 1.6.1
This fix is included in ruby >= 2.7.2
