CVSS 5.900000095367432 MEDIUM
A flaw was found in Netty. There is an issue where the content-length header is not validated correctly if the request uses a single Http2HeaderFrame with the endstream set to true. This flaw leads to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. The highest threat from this vulnerability is to integrity.
