GitHub Vulnerability Alerts

CVE-2025-59414

Summary

A client-side path traversal vulnerability in Nuxt's Island payload revival mechanism allowed attackers to manipulate client-side requests to different endpoints within the same application domain when specific prerendering conditions are met.

Technical Details

The vulnerability occurs in the client-side payload revival process (revive-payload.client.ts) where Nuxt Islands are automatically fetched when encountering serialized __nuxt_island objects. The issue affects the following flow:

  1. During prerendering, if an API endpoint returns user-controlled data containing a crafted __nuxt_island object
  2. This data gets serialized with devalue.stringify and stored in the prerendered page
  3. When a client navigates to the prerendered page, devalue.parse deserializes the payload
  4. The Island reviver attempts to fetch /__nuxt_island/${key}.json where key could contain path traversal sequences

Prerequisites for Exploitation

This vulnerability requires all of the following conditions:

  1. Prerendered pages: The application must use Nuxt's prerendering feature (nitro.prerender)
  2. Attacker-controlled API responses: The attacker must be able to control the response content of an API endpoint that is called during prerendering via useFetch, useAsyncData, or similar composables
  3. Client-side navigation: A user must navigate to the prerendered page (not during initial SSR hydration)

Attack Scenario

// Malicious API response during prerendering
{
  "__nuxt_island": {
    "key": "../../../../internal/service",
    "params": { "action": "probe" }
  }
}

This could cause the client to make requests to /__nuxt_island/../../../../internal/service.json if path traversal is not properly handled by the server.

Impact Assessment

  • Limited Impact: The vulnerability has a low severity due to the highly specific prerequisites
  • No Direct Data Exfiltration: The vulnerability does not directly expose sensitive data
  • Client-Side Only: Requests originate from the client, not the server

Mitigation

Action Required:

  • Update to Nuxt 3.19.0+ or 4.1.0+ immediately
  • Review any prerendered pages that fetch external or user-controlled data

Temporary Workarounds (if immediate update is not possible):

  1. Disable prerendering for pages that fetch user-controlled data
  2. Implement strict input validation on API endpoints used during prerendering
  3. Use allowlists for API response structures during prerendering

Fix Details

The fix implemented validation for Island keys in revive-payload.server.ts:

  • Island keys must match the pattern /^[a-z][a-z\d-]*_[a-z\d]+$/i
  • Maximum length of 100 characters
  • Prevents path traversal and special characters

v3.18.0

Compare Source

3.18.0 is the next minor release.

👀 Highlights

A huge thank you to everyone who's been a part of this release, which is mostly about backporting features + bugfixes from Nuxt v4.

Over the next six months, we'll continue backporting compatible v4 features and bug fixes, so please keep the feedback coming! ❤️

🧪 Lazy Hydration Macros

Building on the delayed hydration support from v3.16, we now support lazy hydration macros (#​31192)! These provide a more ergonomic way to control component hydration:

<script setup lang="ts">
const LazyHydrationMyComponent = defineLazyHydrationComponent(
  'visible',
  () => import('./components/MyComponent.vue')
)
</script>
<template>
  <div>
    <!-- 
      Hydration will be triggered when
      the element(s) is 100px away from entering the viewport.
    -->
    <LazyHydrationMyComponent :hydrate-on-visible="{ rootMargin: '100px' }" />
  </div>
</template>

These macros make it possible to use Nuxt's lazy hydration utilities alongside explicit component imports.

♿️ Accessibility Improvements

We've enhanced accessibility by including <NuxtRouteAnnouncer> in the built-in app.vue (#​32621). This means page changes will be announced to screen readers, making navigation more accessible for users with visual impairments. (This only applies if you do not have an app.vue in your project. If you do, please keep <NuxtRouteAnnouncer> in your app.vue!)

🛠️ Enhanced Development Experience
Chrome DevTools Workspace Integration

We've added Chrome DevTools workspace integration (#​32084), allowing you to edit your Nuxt source files directly from Chrome DevTools. This creates a better debugging experience where changes made in DevTools are reflected in your actual source files.

Better Component Type Safety

Component type safety has been improved with:

  • Typed slots for <ClientOnly> and <DevOnly> (#​32707) - better IntelliSense and error checking
  • Exported <NuxtTime> prop types (#​32547) - easier to extend and customize
New Auto-Import: onWatcherCleanup

The onWatcherCleanup function from vue is now available as an auto-import (#​32396), making it easier to clean up watchers and prevent memory leaks:

const { data } = useAsyncData('users', fetchUsers)

watch(data, (newData) => {
  const interval = setInterval(() => {
    // Some periodic task
  }, 1000)
  
  // Clean up when the watcher is stopped
  onWatcherCleanup(() => {
    clearInterval(interval)
  })
})
📊 Observability Enhancements

Page routes are now exposed to Nitro for observability (#​32617), enabling better monitoring and analytics integration with supported platforms. This allows observability tools to track page-level metrics more effectively.

🔧 Module Development Improvements

Module authors get several quality-of-life improvements:

Simplified Server Imports

The addServerImports kit utility now supports single imports (#​32289), making it easier to add individual server utilities:

// Before: had to wrap in array
addServerImports([{ from: 'my-package', name: 'myUtility' }])

// Now: can pass directly
addServerImports({ from: 'my-package', name: 'myUtility' })
TypeScript Configuration

Modules can now add to typescript.hoist (#​32601), giving them more control over TypeScript configuration and type generation.

⚡️ Performance Improvements

We've made several performance optimizations:

  • Improved Vite-node communication via internal socket (#​32417) for faster development builds
  • Migration to oxc-walker (#​32250) and oxc for onPrehydrate transforms (#​32045) for faster code transformations
🐛 Bug Fixes

This release also includes several important fixes:

  • Improved data fetching: When computed keys change, old data is now properly retained (#​32616)
  • Better scroll behavior: scrollBehaviorType is now only used for hash scrolling (#​32622)
  • Fixed directory aliases: Added trailing slashes to some directory aliases for better consistency (#​32755)
✅ Upgrading

As usual, our recommendation for upgrading is to run:

npx nuxi@latest upgrade --dedupe

This refreshes your lockfile and pulls in all the latest dependencies that Nuxt relies on, especially from the unjs ecosystem.
