In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's STOMP encoder (\u00a0StompSubframeEncoder\u00a0) does not escape or validate header values in \u00a0CONNECT\u00a0 and \u00a0CONNECTED\u00a0 frames, so raw newline (\u00a0\\n\u00a0) characters in a header value are written directly to the wire, allowing an attacker who controls a header value to inject additional STOMP headers. This happens because the encoder intentionally skips escaping for CONNECT/CONNECTED frames per the STOMP 1.2 specification but never rejects the raw newlines, and since a broker parses each line as a separate header, an attacker controlling a value such as a user-supplied login or passcode can overwrite connection parameters or add authentication/role headers to bypass authentication or escalate privileges (the actual impact is broker-dependent). The issue is fixed in versions 4.1.136.Final and 4.2.16.Final."}], "source": {"advisory": "GHSA-3g8r-4pfx-jmfh", "discovery": "UNKNOWN"}}}}
