Description Avinash Hanwate 2026-08-05 14:16:46 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

In Eclipse Jetty, a first HTTP/1.1 request with trailers causes the server to retain the trailers in subsequent requests performed over the same connection.
Subsequent request that do not have trailers report the trailers of the first request.
Subsequent request that do have trailers report the union of trailers of the first request and the current request.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
