What is CVE-2022-41915?

The Netty framework, an event-driven asynchronous network application framework, is susceptible to an HTTP response splitting vulnerability due to inadequate validation of header values when using the DefaultHttpHeaders.set method with an iterator. This flaw allows malicious users to manipulate header values, posing risks to affected applications. The issue has been resolved in version 4.1.86.Final. Users are advised to implement workarounds by replacing set calls with remove followed by add operations on the iterator.
