CVE-2026-59177 is an authentication-bypass vulnerability in the ESPHome Home Assistant add-on ingress dashboard. In affected host-network deployments, the dashboard's intentionally unauthenticated ingress service binds to all network interfaces rather than being restricted to the Home Assistant Supervisor path. Direct access from the local network bypasses Supervisor ingress authentication, granting an unauthenticated user the same effective dashboard capabilities as an authenticated caller. The issue is classified as CWE-1327, Binding to an Unrestricted IP Address.

A high-severity vulnerability affecting esphome-device-builder and related packages prior to version 1.0.10. It has a CVSS v3 base score of 8.8 and may impact confidentiality, integrity, and availability.
An adjacent-network authentication-bypass vulnerability in the ESPHome Device Builder Dashboard Home Assistant add-on. Its unauthenticated ingress service was exposed on all host interfaces, allowing local-network clients to bypass the Home Assistant Supervisor ingress proxy and gain dashboard access with host-equivalent capabilities, including arbitrary code execution during compilation and read/write access to mounted configuration and data directories.
An adjacent-network authentication bypass in the ESPHome Device Builder/Home Assistant add-on ingress dashboard. Binding the trusted, unauthenticated ingress service to all interfaces exposed it on the host LAN; an unauthenticated local-network client could gain full dashboard capability, including arbitrary compile-time Python/shell execution and access to mounted configuration and data directories.
