Nuxt Devtools has a Path Traversal: '../filedir'

CVE-2024-23657 / GHSA-rcvg-rgf7-pppv

More information

Details

Summary

Nuxt Devtools is missing authentication on the getTextAssetContent RPC function which is vulnerable to path traversal. Combined with a lack of Origin checks on the WebSocket handler, an attacker is able to interact with a locally running devtools instance and exfiltrate data abusing this vulnerability.

In certain configurations an attacker could leak the devtools authentication token and then abuse other RPC functions to achieve RCE.

Details

The getTextAssetContent function does not check for path traversals (source), this could allow an attacker to read arbitrary files over the RPC WebSocket.

The WebSocket server does not check the origin of the request (source) leading to CSWSH. This may be intentional to allow certain configurations to work correctly.

Nuxt Devtools authentication tokens are placed within the home directory of the current user (source).

In the scenario that:

• The user has a Nuxt3 Project running
• Devtools is enabled and running
• The project is placed within the users home directory.
• The user visits a malicious webpage
• User has authenticated with devtools at least once

The malicious webpage can connect to the Devtools WebSocket, perform a directory traversal brute force to find the authentication token, then use the authenticated writeStaticAssets function to create a new Component, Nitro Handler or app.vue file which will run automatically as the file is changed.

PoC

POC will exploit the Devtools server on localhost:3000 (you may need to manually restart the server as the restart hook does not always work).

POC: https://devtools-exploit.pages.dev

1. Create a new project with nuxt.new.
2. Place the project inside your home directory.
3. Run pnpm run dev.
4. Open the POC page.

The POC will:

• Identify devtools version.
• Leak your devtools token.
• Create a new server handler with an insecure eval.

Impact

• All new Nuxt projects by default (devtools is enabled) are vulnerable to arbitrary file read.
• Certain Nuxt configurations are vulnerable to Remote Code Execution

Nuxt DevTools vulnerable to cross-site scripting (XSS)

CVE-2025-52662 / GHSA-xmq3-q5pm-rp26

More information

Details

A vulnerability in Nuxt DevTools has been fixed in version 2.6.4*. This issue may have allowed Nuxt auth token extraction via XSS under certain configurations. All users are encouraged to upgrade.

Unauthenticated Nuxt DevTools RPC allows arbitrary command execution on the developer's host

CVE-2026-71319 / GHSA-279x-mwfv-vcqv

More information

Details

Impact

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.

The HMR port is reachable by a process on the same host, by any peer on the LAN when the dev server is bound with nuxi dev --host, or by a malicious website the developer visits while the dev server is running (a browser can open the HMR WebSocket cross-origin). Impact is limited to development environments; production builds do not run DevTools.

Patches

Fixed in @nuxt/devtools@3.3.1. Because nuxt depends on @nuxt/devtools through a ^3.x range, updating is a lockfile refresh / reinstall; no nuxt release is required.

Workarounds

• Update @nuxt/devtools to a patched version.
• Do not run the dev server bound to a non-loopback interface (nuxi dev --host) on an untrusted network.
• Disable DevTools entirely with devtools: { enabled: false } in nuxt.config.
