Summary: Possible request smuggling in HTTP/2 due missing validation of content-length
Details: ### Impact The content-length header is not correctly validated if the request only use a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1 This is a followup of https://github.com/netty/netty/security/advisories/GHSA-wm47-8v5p-wjpj which did miss to fix this one case. ### Patches This was fixed as part of 4.1.61.Final ### Workarounds Validation can be done by the user before proxy the request by validating the header.
