Description
Description
ESPHome Device Builder Dashboard is a dashboard for the ESPHome home management software. 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.
