-            Heads up: the legacy ESPHome dashboard (\`esphome/dashboard/\` and \`tests/dashboard/\`) is **deprecated** and is being replaced by [ESPHome Device Builder](https://github.com/esphome/device-builder). We are not adding new features to the legacy dashboard and it will eventually be removed from this repository.
-
-            What this means for your PR:
-
-            - **New features / enhancements**: please port the change to [esphome/device-builder](https://github.com/esphome/device-builder) instead. We are unlikely to review or merge new dashboard features here.
-            - **Bug fixes**: small fixes may still be considered, but please check first whether the same issue exists in Device Builder, where the fix will have a longer life.
-            - **Security issues**: please do not file a public PR. Report privately via [GitHub security advisories](https://github.com/esphome/esphome/security/advisories/new) so we can coordinate a fix.
-
-            We appreciate the contribution and apologize for the friction; flagging this early so your time isn't spent on a change that may not land.

+# ESPHome Threat Model
+
+This document defines the trust boundary for the **ESPHome** repository — the
+Python compiler/CLI and the device firmware it generates — so that real security
+bugs can be told apart from defense-in-depth improvements. It gives contributors,
+reviewers, and security researchers a clear answer to one question:
+**does this issue let an _unauthenticated_ attacker do something they shouldn't?**
+
+Related documents:
+
+- Deployment guidance for operators:
+  https://esphome.io/guides/security_best_practices/
+- The **Device Builder dashboard** (the web UI, its authentication, ingress,
+  Origin/Host gates, and peer-link pairing) lives in a separate repository and
+  has its own threat model. If your report concerns any of that, please read and
+  report there instead:
+  https://github.com/esphome/device-builder/blob/main/docs/THREAT_MODEL.md
+
+## The trust boundary
+
+For this repository there are two trusted inputs by design:
+
+1. **The configuration.** Anyone who can supply or edit a YAML config is trusted
+   (see below).
+2. **Authenticated peers of a running device** — clients holding the device's
+   API encryption key / password, OTA password, or web server credentials.
+
+The security boundary is therefore **unauthenticated network traffic vs. those
+trusted inputs.** A bug that lets an unauthenticated attacker cross it is a
+security bug.
+
+## Config authors are host-equivalent by design
+
+Anyone who can supply or edit a configuration is **trusted with full code
+execution on the host that runs `esphome`**, on purpose. This is what the product
+does, not a flaw. A config author can already, through fully supported features:
+
+- Run arbitrary **Python** at validation/compile time via `external_components:`
+  (and other component-import mechanisms) — ESPHome imports those packages as
+  ordinary Python.
+- Run arbitrary **shell** commands through the compile/validate/flash toolchain
+  that ESPHome invokes as subprocesses.
+- Read and write arbitrary files reachable by the process (e.g. via `!include`,
+  `packages:`, `dashboard_import:`, and generated build output).
+
+Because of this, a malicious config author is equivalent to shell access on the
+host running the build.
+
+## What is *not* a security vulnerability
+
+If exploiting an issue requires the ability to supply or edit configuration, it
+is **not** a vulnerability in ESPHome, because that ability already grants host
+code execution. This explicitly includes, among others:
+
+- Template / expression injection in substitutions or any YAML string value
+  (e.g. Jinja `${...}` evaluation reaching Python internals). This grants no
+  capability a config author lacks.
+- `!include` / `packages:` / `dashboard_import:` reading or fetching content
+  from surprising or remote locations.
+- The validator or compiler crashing or behaving unexpectedly on adversarial
+  YAML.
+- ESPHome running as root in the official container — that is the documented
+  deployment posture, reachable by the same caller through the features above.
+
+These do not warrant a CVE or coordinated disclosure. Hardening in these areas
+(for example, sandboxing template evaluation as least-surprise defense-in-depth)
+is welcome as a normal enhancement PR, framed as cleanliness rather than a
+security fix — not as a vulnerability remediation.
+
+## What we do defend
+
+These *are* security bugs in this repo, and we want to hear about them privately:
+
+- Memory-safety or protocol bugs in the generated **device firmware** that are
+  remotely triggerable over the network (native API, web server, OTA, BLE,
+  captive portal, etc.) **without** valid credentials.
+- Authentication or encryption bypass on the device — reaching API calls, OTA
+  updates, or the web server without the configured key/password.
+- Flaws that weaken the device's API encryption (Noise), OTA, or web server auth
+  below their documented guarantees.
+
+## The web server is an open HTTP API by design
+
+The `web_server` component exposes a plain HTTP interface for viewing and
+controlling entities, and, when the `web_server` OTA platform is enabled, for
+uploading firmware at `/update`. Its only access controls are the optional
+`web_server` `auth:` credentials and the network the device sits on.
+
+When `auth:` is not configured, every endpoint is reachable by any client that
+can reach the device. This is intentional; enabling `web_server` without `auth:`
+is choosing an open control surface, in the same way that running native OTA
+without a password leaves OTA open. The API is documented and is meant to be
+called by other devices, scripts, and pages.
+
+As defense-in-depth, the web server checks the `Origin` header on browser requests
+to its entity control and state endpoints: a request whose `Origin` does not match
+the address the device is served on is rejected, and the `allowed_origins` option
+widens that list. This blocks the common "confused deputy" (CSRF) case where a page
+the operator visits drives the device through their browser. It is **not** an
+authentication boundary: it only constrains browsers. Any client that omits the
+`Origin` header — `curl`, scripts, or other non-browser callers on the same
+network — reaches every endpoint exactly as before. The check also does not cover
+the web OTA `/update` endpoint. The device performs no CSRF-token or `Referer`
+validation. The following are therefore **not** vulnerabilities in this repository:
+
+- Requests without an `Origin` header (for example `curl`) reaching the control
+  endpoints, whether or not `web_server` `auth:` is set.
+- Requests from an origin the operator added to `allowed_origins`.
+- Cross-origin or CSRF firmware upload through the web OTA endpoint (`/update`) when
+  web OTA is enabled without `web_server` `auth:`. The `/update` endpoint is not
+  covered by the `Origin` check; this is the same exposure as running OTA without a
+  password.
+
+The supported defenses are `web_server` `auth:`, protecting OTA (a web password or
+a native OTA password), and keeping devices on a trusted, segmented network. See
+the security best practices guide linked above.
+
+What remains in scope is bypassing `web_server` `auth:` when it *is* configured,
+and any memory-safety or protocol bug in the server reachable without credentials.
+
+This section documents the current design and scope; it is not a judgment that the
+design is optimal or that it will not change.
+
+## Explicitly out of scope
+
+- Local attackers who already have shell access on the host that runs `esphome`.
+- Supply-chain attacks against ESPHome or its dependencies.
+- Operator-supplied hostile YAML (covered above — config authoring is trusted).
+- Attacks that require an already-authenticated device peer (someone who already
+  holds the API key / OTA / web credentials).
+- Access to the device web server or its web OTA endpoint by non-browser clients
+  (those that send no `Origin` header). The web server is an open HTTP API by
+  design (see above); browser cross-origin requests are blocked by default, but the
+  real controls are `web_server` `auth:` and network isolation.
+- Anything in the dashboard / device-builder — report that in its own repository
+  (linked at the top).
+- Deployments where the operator removed protections or exposed credentials. See
+  the security best practices guide:
+  https://esphome.io/guides/security_best_practices/
+
+## Reporting a vulnerability
+
+If you believe you've found an issue that crosses the unauthenticated boundary
+above, please report it privately via GitHub Security Advisories rather than a
+public issue. For issues that require config-write access, please review this
+document first — they are very likely out of scope by design. For dashboard /
+device-builder issues, report against that repository and consult its threat
+model (linked at the top).

+# module only keeps the deprecated top-level `animation:` key working during the
+# deprecation window: it reuses that schema/codegen and adds a one-shot
+# deprecation warning (with a pasteable migrated `image:` block) at validation
+# time. Deleting this file drops the top-level form entirely.
