Description OSIDB Bzimport 2026-07-27 14:37:34 UTC 
Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final, the STOMP decoder in netty-codec-stomp fails to properly neutralize CR/LF sequences in STOMP protocol frames. An attacker can craft malformed STOMP commands with embedded CR/LF sequences to inject arbitrary protocol frames, bypassing message boundary checks and potentially causing command injection. This issue is fixed in versions 4.1.136.Final and later.
