A Nuxt Devtools le falta autenticaci\u00f3n en la funci\u00f3n RPC `getTextAssetContent`, que es vulnerable a path traversal. Combinado con la falta de comprobaciones de origen en el controlador WebSocket, un atacante puede interactuar con una instancia de devtools que se ejecuta localmente y extraer datos abusando de esta vulnerabilidad. En determinadas configuraciones, un atacante podr\u00eda filtrar el token de autenticaci\u00f3n de devtools y luego abusar de otras funciones RPC para lograr RCE. La funci\u00f3n `getTextAssetContent` no comprueba los path traversal, lo que podr\u00eda permitir a un atacante leer archivos arbitrarios a trav\u00e9s del RPC WebSocket. El servidor WebSocket no verifica el origen de la solicitud, lo que conduce al secuestro de websocket entre sitios. Esto puede ser intencionado para permitir que ciertas configuraciones funcionen correctamente. Los tokens de autenticaci\u00f3n de Nuxt Devtools se colocan dentro del directorio de inicio del usuario actual. La p\u00e1gina web maliciosa puede conectarse al WebSocket de Devtools, realizar un directory traversal por fuerza bruta para encontrar el token de autenticaci\u00f3n y luego usar la funci\u00f3n *autenticada* `writeStaticAssets` para crear un nuevo componente, Nitro Handler o archivo `app.vue` que se ejecutar\u00e1 autom\u00e1ticamente a medida que se cambia el archivo. Esta vulnerabilidad se solucion\u00f3 en la versi\u00f3n 1.3.9. Se recomienda a todos los usuarios que actualicen.
