CyberRota Analysis
AI-GeneratedThe NATS Server is vulnerable to a flaw in its WebSocket listener that improperly routes requests to the MQTT handling path, even when MQTT is not configured. This can lead to an unauthenticated client crashing the server by accessing uninitialized MQTT state. Organizations using affected versions should prioritize upgrading to versions 2.14.3 or 2.12.12 to mitigate this risk.

Original NVD Description
NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.3 and 2.12.12, a WebSocket listener could route requests for the MQTT-over-WebSocket path into MQTT handling even when MQTT was not configured, allowing an unauthenticated client with access to the WebSocket listener to reach uninitialized MQTT state and crash the server process. This issue is fixed in versions 2.14.3 and 2.12.12.
