> <dependency>
> <groupId>io.netty</groupId>
> <artifactId>netty</artifactId>
> <version>3.10.6.Final</version>

> I think we should upgrade Netty to its latest version: netty-4.1.45.Final.
> The reasons are as follows:
> The CVE-2019-20445 vulnerability exists in netty-3.10.6.Final:
> HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header
> to be accompanied by a second Content-Length header, or by a
> Transfer-Encoding header. For details see:
