Doc Text:
A flaw was found in the Netty STOMP (Streaming Text Oriented Messaging Protocol) decoder. This vulnerability allows a remote attacker to inject arbitrary protocol frames by crafting malformed STOMP commands that contain embedded carriage return (CR) and line feed (LF) sequences. This bypasses message boundary checks and can lead to command injection, potentially compromising the integrity of the system.

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.
