CVE-2026-72744

### Impact When a Nuxt dev server is bound to a network-reachable interface (for example `nuxt dev --host` for on-device testing), the default-enabled Chrome DevTools workspace endpoint `GET /.well-known/appspecific/com.chrome.devtools.json` returns the absolute project root (`workspace.root`, i.e. `rootDir`) and a persistent per-project workspace UUID. `GHSA-rq7w-g337-39qq` added a gate (`isLocalDevRequest`) intended to restrict this endpoint to local requests, but that gate is header-based: it trusts request metadata rather than the connected peer address. A request with no `Sec-Fetch-Site`, `Origin`, and `Referer` headers (normal for a non-browser client such as `curl`) is treated as local, and the `Host` allow-list is compared against the attacker-supplied `Host` header. As a result, any unauthenticated host that can reach the dev server on the LAN can retrieve the project's absolute filesystem path and workspace UUID, for example with `curl -H 'Host: localhost' http://<dev-host-lan-ip>:3000/.well-known/appspecific/com.chrome.devtools.json`. This is information disclosure only: there is no file read, file write, or code execution reachable from the endpoint. It requires the dev server to be reachable beyond loopback and `experimental.chromeDevtoolsProjectSettings` to be enabled (it defaults to `true`). Production builds are unaffected, because the endpoint is registered only as a development handler. ### Patches Fixed in `[email protected]` and `[email protected]`. The endpoint now additionally requires the connected TCP peer to be a loopback address, verified from the socket rather than from request headers, so a non-loopback LAN client is rejected regardless of the `Host`, `Origin`, `Referer`, or `Sec-Fetch-*` headers it sends. The shared header-based check is left unchanged, so the CSRF / same-origin behaviour that other dev handlers rely on is preserved. After this fix, Chrome DevTools workspace auto-mapping only works when the browser reaches the dev server over l
