An issue was discovered in the WEBrick toolkit through 1.8.1 for Ruby. It allows HTTP request smuggling by providing both a Content-Length header and a Transfer-Encoding header, e.g., GET /admin HTTP/1.1rn inside of a POST /user HTTP/1.1rn request. NOTE: the suppliers position is Webrick should not be used in production.
