GitHub Vulnerability Alerts

CVE-2025-53892

Summary

The escapeParameterHtml: true option in Vue I18n is designed to protect against HTML/script injection by escaping interpolated parameters. However, this setting fails to prevent execution of certain tag-based payloads, such as <img src=x onerror=...>, if the interpolated value is inserted inside an HTML context using v-html.

This may lead to a DOM-based XSS vulnerability, even when using escapeParameterHtml: true, if a translation string includes minor HTML and is rendered via v-html.

Details

When escapeParameterHtml: true is enabled, it correctly escapes common injection points.

However, it does not sanitize entire attribute contexts, which can be used as XSS vectors via:

<img src=x onerror=alert(1)>

PoC

In your Vue I18n configuration:

const i18n = createI18n({
  escapeParameterHtml: true,
  messages: {
    en: {
      vulnerable: 'Caution: <img src=x onerror="{payload}">'
    }
  }
});

Use this interpolated payload:

const payload = '<script>alert("xss")</script>';
Render the translation using v-html (even not using v-html):

<p v-html="$t('vulnerable', { payload })"></p>
Expected: escaped content should render as text, not execute.

Actual: script executes in some environments (or the payload is partially parsed as HTML).

Impact

This creates a DOM-based Cross-Site Scripting (XSS) vulnerability despite enabling a security option (escapeParameterHtml) .

We are excited to announce the release of Vue I18n v9.3, finally !! This release includes some new features, bug fixes, improvements, and document fixes.

We had commited with 37 contributors. Thanks for your contributing ❤️

In the following, we introduce some of the new features:

🌟 Features

Node.js Dual packages (cjs / mjs)

We provide CommonJS and Native ESM dual module packages for Node.js. This supports both require and import for loading modules in Node.js.

JIT Style Compilation

Supports JIT (Just In Time) style compilation of message formats. This mean, removes the CSP limitation and allows for use in environments such as Service worker, Web worker, and Edge.

It mean also now supports the use-case where locale messages are dynamically retrieved from the backend via the API.

For more information, please see the docs

The performance of JIT-style compilation is close to that of conventional AOT (Ahead Of Time) style compilation, and you can improve the performance to nearly 3x with combination of JIT + AOT.

Below are the compile performance benchmark results for vue-i18n:

> node ./benchmark/index.mjs

compilation:

compile simple message x 396,898 ops/sec ±0.31% (98 runs sampled)
compile complex message x 60,036 ops/sec ±0.34% (99 runs sampled)

simple pattern on 1000 resources (AOT):

resolve time with core x 279,919 ops/sec ±0.19% (99 runs sampled)
resolve time on composition x 93,963 ops/sec ±0.48% (93 runs sampled)
resolve time on composition with compile cache x 230,928 ops/sec ±0.20% (100 runs sampled)

simple pattern on 1000 resources (JIT):

resolve time with core x 277,813 ops/sec ±0.18% (99 runs sampled)
resolve time on composition x 91,959 ops/sec ±0.43% (97 runs sampled)
resolve time on composition with compile cache x 227,117 ops/sec ±0.15% (99 runs sampled)

simple pattern on 1000 resources (JIT + AOT):

resolve time with core x 319,061 ops/sec ±0.18% (100 runs sampled)
resolve time on composition x 204,529 ops/sec ±0.22% (95 runs sampled)
resolve time on composition with compile cache x 204,652 ops/sec ±0.30% (100 runs sampled)

complex pattern on 1000 resources (AOT):

resolve time with core x 240,427 ops/sec ±0.37% (100 runs sampled)
resolve time on composition x 33,959 ops/sec ±0.45% (94 runs sampled)
resolve time on composition with compile cache x 200,980 ops/sec ±0.15% (99 runs sampled)

complex pattern on 1000 resources (JIT):

resolve time with core x 225,739 ops/sec ±0.25% (99 runs sampled)
resolve time on composition x 36,379 ops/sec ±0.49% (97 runs sampled)
resolve time on composition with compile cache x 191,653 ops/sec ±0.24% (100 runs sampled)

complex pattern on 1000 resources (JIT + AOT):

resolve time with core x 278,542 ops/sec ±0.20% (98 runs sampled)
resolve time on composition x 92,781 ops/sec ±0.31% (98 runs sampled)
resolve time on composition with compile cache x 92,865 ops/sec ±0.33% (98 runs sampled)

You can clone Vue I18n and run the benchmark with pnpm build:type && pnpm benchmark to check.

Custome message format

Starting with v9.3, Vue I18n will give message format customization as an experimental feature. This will allow for extending to the message format:

import { createI18n } from 'vue-i18n'
import { messageCompiler } from './compilation'

const i18n = createI18n({
  legacy: false,
  locale: 'en',
  messageCompiler,
  messages: {
    en: {
      hello: 'hello world!',
      greeting: 'hi, {name}!',
      photo: `You have {numPhotos, plural,
        =0 {no photos.}
        =1 {one photo.}
        other {# photos.}
      }`
    }
  }
})

About details, please see the docs

Exports type definition and API

Export v-t type definitions and API $te to support Vue I18n extending for third vendors and your Vue applications.

❗ Important Changes: 1

allowComposition option

The allowComposition option will be removed in Vue I18n v10. We have accordingly output a warning if you are using it.

If you are using Vue I18n Legacy API to migrate to the Composition API, please make sure you have done so with the Vue I18n v9 version.

Deprecate vue-i18n official bundle plugins

The following plugin or loader for bundler is deprecated because it can be replaced by the unplugin-vue-i18n.

These will only be taken as hot fixes in the future, and no additional functionality will be added.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai explain this code block.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and explain its main purpose.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Join our Discord community for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
