How to fix?
io.netty:netty-codec to version 4.1.46.Final or higher.
io.netty:netty-codec is an event-driven asynchronous network application framework.
Affected versions of this package are vulnerable to Uncontrolled Memory Allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
