Netty versions prior to 4.1.136.Final and 4.2.16.Final have a vulnerability in HttpPostRequestEncoder where multipart HTTP request bodies are constructed by directly concatenating user-supplied filenames and field names into Content-Disposition MIME headers without sanitizing CRLF characters. This allows an attacker controlling the filename to inject arbitrary MIME headers into the multipart body part. The issue is fixed in versions 4.1.136.Final and 4.2.16.Final.
