Upgrade @nuxt/devtools to version 3.3.1 or higher.
Overview
@nuxt/devtools is a 
Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the nuxt:devtools:rpc. An attacker can execute arbitrary commands on the host system by sending crafted RPC calls to the exposed WebSocket endpoint without authentication.
Note: This is only exploitable if the development server is running and accessible to the attacker, such as when bound to a non-loopback interface or when the developer visits a malicious website while the server is active.
Workaround
This vulnerability can be mitigated by disabling DevTools entirely with the configuration option devtools: { enabled: false } or by avoiding running the development server on a non-loopback interface in untrusted environments.
