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.
