## Overview

Nuxt is an open-source web development framework for Vue.js. Prior to 3.3.1, Nuxt DevTools (development mode only) exposes a bidirectional RPC channel over the Vite HMR WebSocket via the nuxt:devtools:rpc plugin. On affected versions the channel has no authentication: any client that can reach the Vite HMR endpoint (ws://<host>:<port>/, subprotocol vite-hmr) can call RPC methods, with no token, handshake, or origin check before the channel is established. The updateOptions(), clearOptions(), and openInEditor() methods do not enforce the ensureDevAuthToken check that the other mutating methods use. openInEditor() reads the persisted behavior.openInEditor value and passes it to the launch-editor package, which spawns it as a child process. That value is settable through the equally unauthenticated updateOptions(). An attacker who can reach the HMR port can therefore chain updateOptions('behavior', { openInEditor: '<command>' }) then openInEditor('<any-existing-file>') to execute an arbitrary program on the developer's machine. This issue is fixed in 3.3.1.
