Affected packages

• Maven org.apache.tomcat:tomcat-coyote: >= 10.0.0-M1, < 10.0.0-M10 → fixed in 10.0.0-M10 • Maven org.apache.tomcat:tomcat-coyote: >= 9.0.0-M1, < 9.0.40 → fixed in 9.0.40 • Maven org.apache.tomcat:tomcat-coyote: >= 8.5.0, < 8.5.60 → fixed in 8.5.60

Description

While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.
