GHSA-4vww-mc66-62m6 HTTP Request Smuggling in Apache Tomcat

• Maven org.apache.tomcat:tomcat: >= 10.0.0-M1, < 10.0.7 → fixed in 10.0.7 • Maven org.apache.tomcat:tomcat: >= 9.0.0-M1, < 9.0.48 → fixed in 9.0.48 • Maven org.apache.tomcat:tomcat: >= 8.5.0, < 8.5.68 → fixed in 8.5.68

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 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.
