    "summary": "The EmbeddedHeadersJsonMessageMapper defaults to an overly permissive header parsing posture in its constructor. When decodeNativeFormat processes raw byte payloads, it deserializes embedded JSON headers into a plain Map and constructs a GenericMessage with MutableMessageHeaders without sanitizing or filtering untrusted header names by default.
