Apache Tomcat 7.0.X, 8.0.X, 8.5.0 to 8.5.66, 9.0.0.M1 to 9.0.46, and 10.0.0-M1 to 10.0.6, did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
