reactor-netty-http can mis-evaluate the remote IP address when HAProxy Protocol is enabled. Access-control or logging decisions that trust that address may then use the wrong client identity. The issue only applies when the server is configured to use HAProxy Protocol. The patch correctly derives the remote address from the proxy protocol data.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and HAProxy Protocol is enabled on the Reactor Netty HTTP server.
