These credentials are publicly documented on github, and there is no indication in the instructions to change them. A remote attacker can use them to gain full read and write access to the broker, allowing control of connected relays, blinds, and gates, and injection of fake entities into a linked Home Assistant installation.\n\nThis issue was fixed in version 1.6.0 of the image: MQTT passwords are generated per device at first boot. Devices upgraded from earlier versions keep their existing broker credentials; from boneio 1.6.0 the web panel reports credentials that are still the published defaults, and the owner has to change them.","state":0,"publishedAt":"2026-10-26T14:45:53.279+00:00","modifiedAt":"2026-10-26T16:46:44.867+00:00","affected":[{"ecosystem":"Vendor product","name":"black_debian_images","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"boneIO\",\n                    \"product\": \"black_debian_images\",\n                    \"repo\": \"https://github.com/boneIO-eu/black_debian_images\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.2.0\",\n                            \"lessThan\": \"1.6.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"}],"references":["https://cert.pl/en/posts/2026/10/CVE-2026-77052","https://boneio.eu/en/docs/black"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77056","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77056","identifiers":["CVE-2026-77056"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
