If an HTTP/2 client connecting to Apache Tomcat between 10.0.0-M1 and 10.0.0-M7, between 9.0.0.M1 and 9.0.37, and between 8.5.0 and 8.5.57 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.
