GHSA-f268-65qc-98vg Exposure of Sensitive Information to an Unauthorized Actor in Apache Tomcat

• Maven org.apache.tomcat:tomcat-coyote: >= 10.0.0-M1, < 10.0.0-M8 → fixed in 10.0.0-M8 • Maven org.apache.tomcat:tomcat-coyote: >= 9.0.0-M1, < 9.0.38 → fixed in 9.0.38 • Maven org.apache.tomcat:tomcat-coyote: >= 8.5.0, < 8.5.58 → fixed in 8.5.58

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