[anupamme]

Summary

Fix high severity security issue in main.js.

Vulnerability

Field	Value
ID	V-001
Severity	HIGH
Scanner	multi_agent_ai
Rule	V-001
File	main.js:1
Assessment	Likely exploitable
Chain Complexity	5-step

Description: The adapter configuration includes an optional 'Do not verify user and password' setting for MQTT connections. While username and password fields exist, they are not enforced, allowing administrators to disable authentication entirely. This creates a configuration-dependent vulnerability where the MQTT broker can accept unauthenticated connections if security is disabled.

Evidence

Exploitation scenario: An attacker with network access to the MQTT broker port can connect without credentials if the administrator has disabled authentication.

Scanner confirmation: multi_agent_ai rule V-001 flagged this pattern.

Production code: This file is in the production codebase, not test-only code.

Threat Model Context

This is a Node.js library - vulnerabilities affect downstream consumers who use this package.
