      <title>GHSA-vv4j-m4vr-f3g6 — ESPHome Device Builder Dashboard: Unauthenticated dashboard access via the HA add-on ingress site bound to all interfac…</title>
      <link>https://db.gcve.eu/vuln/ghsa-vv4j-m4vr-f3g6</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; PyPI: esphome-device-builder&lt;/p&gt;
&lt;p&gt;## Summary&lt;/p&gt;
&lt;p&gt;On the Home Assistant add-on, the dashboard serves a trusted ingress site that skips authentication because the supervisor authenticates the request upstream. That site was binding `0.0.0.0`. The add-on runs in host network mode for mDNS, so binding all interfaces also bound the host&amp;#39;s LAN interface, and any device on the local network could reach `http://&amp;lt;ha-ip&amp;gt;:&amp;lt;ingress_port&amp;gt;/` and get the full dashboard with no credentials.&lt;/p&gt;
&lt;p&gt;## Details&lt;/p&gt;
&lt;p&gt;The HA add-on ingress site is intentionally unauthenticated: the supervisor&amp;#39;s ingress proxy authenticates the browser upstream, and the dashboard&amp;#39;s threat model assumes the site is reachable only through the supervisor&amp;#39;s docker network. The protection depended on physically binding the site to the supervisor, but the site bound `0.0.0.0` instead. Because the add-on uses host networking, `0.0.0.0` includes the host&amp;#39;s LAN address, so the no-auth site was reachable directly from the LAN, bypassing the supervisor and its authentication entirely.&lt;/p&gt;
&lt;p&gt;This is an auth bypass on a boundary the dashboard explicitly defends. `docs/THREAT_MODEL.md` names, under the surface it still defends, &amp;#34;anything that lets external traffic reach the ingress site without going through the supervisor.&amp;#34; The bug is exactly that.&lt;/p&gt;
&lt;p&gt;The fix, in PR #1565, mirrors what the legacy add-on&amp;#39;s nginx did:&lt;/p&gt;
&lt;p&gt;- Bind the ingress site to loopback plus the supervisor gateway (`127.0.0.1` and `172.30.32.1`) instead of all interfaces. Loopback serves HA core&amp;#39;s host-network ESP…&lt;/p&gt;</description>
