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1.0.10.","score":8.8,"severity":"high","published":"2026-10-28T13:12:14.620Z","modified":"2026-11-02T20:15:52.405Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"esphome","name":"device-builder","platforms":[],"versions":[{"version":"< 1.0.10","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-59177"}],"remediation":[],"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"],"sources":[{"name":"CVE","id":"CVE-2026-59177","modified":"2026-11-02T20:15:52.405Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-59177"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8}],"sourceAffected":[],"observedAt":"2026-11-02T20:23:38.527Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:40:33.739Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-10-28T14:05:37.148Z","attemptedAt":"2026-10-28T14:05:37.148Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-28T14:05:37.146Z","attemptedAt":"2026-10-28T14:05:37.146Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-28T14:05:38.335Z","attemptedAt":"2026-10-28T14:05:38.335Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-28T14:05:37.147Z","attemptedAt":"2026-10-28T14:05:37.147Z"}],"evidence":[{"source":"GitHub Advisory Database","id":"GHSA-vv4j-m4vr-f3g6","url":"https://github.com/advisories/GHSA-vv4j-m4vr-f3g6","modified":"2026-09-09T23:51:27Z","score":8.8,"vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","checkedAt":"2026-10-28T14:05:37.146Z"},{"source":"ENISA EUVD","id":"EUVD-2026-112079","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-112079","modified":"Sep 10, 2026, 11:02:05 AM","score":8.8,"vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","checkedAt":"2026-10-28T14:05:38.335Z"}],"aiSummary":{"text":"ESPHome Device Builder Dashboard versions prior to 1.0.10 allow unauthenticated access via the HA add-on ingress site bound to all interfaces.
