Summary

The Netty framework is susceptible to a vulnerability in the HttpObjectDecoder class, which may allow an attacker to send requests with multiple Content-Length headers or with an accompanying Transfer-Encoding header. This improper handling can lead to unexpected behavior in how the server processes incoming requests, potentially leading to resource exhaustion or denial of service. It is essential for developers using the Netty framework to upgrade to a secure version to mitigate any risks associated with this vulnerability.
