## Overview

MOOS-IvP uFldNodeComms through 24.8.1 trusts the source node identity from the message body rather than validating it from the connection source. Attackers can craft NODE_MESSAGE packets with spoofed source identities to impersonate other nodes and post arbitrary variable notifications without validation.
