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

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.

What happened

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.

About this data

This record was ingested from a data source. Retrieved: Oct 28, 2026, 15:30 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
