Overview
org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.
Affected versions of this package are vulnerable to HTTP Request Smuggling. If an HTTP/2 client connecting to Apache Tomcat exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources.
