CVE-2026-59322
EmbeddedHeadersJsonMessageMapper default gives wire peer full control of MessageHeaders
CVSS Score
6.3
EPSS Score
0.0%
EPSS Percentile
0th
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.
