Does this matter?

Lower severity and no EPSS score yet. Track it; it rarely justifies an emergency change on its own.

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.
