How to fix?
io.netty:netty-codec-http2 to version 4.1.60.Final or higher.
io.netty:netty-codec-http2 is a HTTP2 sub package for the netty library, an event-driven asynchronous network application framework.
Affected versions of this package are vulnerable to HTTP Request Smuggling. If a Content-Length header is present in the original HTTP/2 request, the field is not validated by
Http2MultiplexHandler as it is propagated up.
An additional case of this vulnerability was fixed in 4.1.61.Final (CVE-2021-21409).
