CVE-2026-77052 boneIO CVE debrief

Who should care

Defenders responsible for home automation systems, particularly those using boneIO Black, should assess exposure and apply the fix. IT teams managing local networks and security personnel monitoring for potential threats should also prioritize this vulnerability.

Why it matters

CVE-2026-77052 is a high-severity vulnerability in boneIO Black that allows unauthenticated Node-RED exposure, potentially leading to remote code execution and full control over the home automation system. Defenders should prioritize verifying exposure, applying the fix, and monitoring for suspicious activity.

• Potential remote code execution by unauthenticated attackers on the local network.
• Possible full control over the home automation system by deploying malicious flows.
• Need for verification of exposure and application of the fix in version 1.6.0 or later.
• Potential for monitoring and detection of suspicious Node-RED activity.

Technical summary

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. Defenders should prioritize verifying exposure and applying the fix, as the vulnerability allows for potential remote code execution.

Defensive priority

Defenders should prioritize verifying exposure and applying the fix in version 1.6.0 or later, as the vulnerability allows for potential remote code execution.

Recommended defensive actions

• Verify if boneIO Black is deployed in your environment and if versions prior to 1.6.0 are in use.
• Apply the fix by updating to version 1.6.0 or later.
• Review and restrict access to the Node-RED instance, if applicable.
• Monitor for potential suspicious activity related to Node-RED deployments.
• Track exceptions and retest remediated assets.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The CVE record and source item provide details on the vulnerability, including its CVSS score of 8.7 and affected versions prior to 1.6.0. However, additional information on potential exploitation or specific attack scenarios is limited.
