Hi, The following vulnerability was published for netty. CVE-2021-43797[0]: | Netty is an asynchronous event-driven network application framework | for rapid development of maintainable high performance protocol | servers & clients. Netty prior to version 4.1.7.1.Final skips | control chars when they are present at the beginning / end of the | header name. It should instead fail fast as these are not allowed by | the spec and could lead to HTTP request smuggling. Failing to do the | validation might cause netty to "sanitize" header names before it | forward these to another remote system when used as proxy. This remote | system can't see the invalid usage anymore, and therefore does not do | the validation itself. Users should upgrade to version 4.1.7.1.Final | to receive a patch. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
