A flaw was found in the netty-codec-haproxy component, part of the Netty network application framework. This vulnerability allows a remote attacker to perform protocol-level injection attacks by crafting malformed HAProxy protocol frames that contain embedded carriage return (CR) and line feed (LF) sequences. This can lead to the injection of arbitrary content, potentially disrupting network communication or enabling further attacks.
