Prior to 1.0.10, the `Home Assistant` add-on's trusted `ingress` site binds to `0.0.0.0` while intentionally skipping dashboard authentication because the supervisor is expected to authenticate requests upstream. Host networking, required for mDNS, also binds this no-auth site to the `Home Assistant` host's LAN interface. Any device on that local network can therefore connect directly to the `ingress` port, bypass the supervisor, and obtain the full dashboard without credentials or operator misconfiguration. Dashboard capability includes compile-time Python execution through `external_components:`, shell execution through compile and validation subprocesses, and arbitrary access to configuration and data files, compromising the mounted `Home Assistant` configuration and managed ESPHome devices. The standalone Docker dashboard and the password-gated public port 6052 are not affected. This issue is fixed in version 1.0.10.","state":0,"publishedAt":"2026-10-28T13:12:14.62+00:00","modifiedAt":"2026-10-28T13:12:14.62+00:00","affected":[{"ecosystem":"Vendor product","name":"device-builder","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"esphome\",\n                    \"product\": \"device-builder\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.0.10\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/esphome/device-builder/security/advisories/GHSA-vv4j-m4vr-f3g6","https://github.com/esphome/device-builder/pull/1565","https://github.com/esphome/device-builder/commit/b6387db3f8bf1d3df5771f40e9856b959ae4f6a1","https://github.com/esphome/device-builder/releases/tag/1.0.10"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59177","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59177","identifiers":["CVE-2026-59177"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
