How to Fix CVE-2025-53892

To remediate this vulnerability, upgrade all affected Vue i18n dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

petite-vue-i18n fixed: 11.1.10 
npm install petite-vue-i18n@11.1.10
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls vue-i18n

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-53892, inspect your project dependencies using npm:

npm ls vue-i18n

Analyze the terminal output to locate any version of Vue i18n in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.14.5), your application is affected.

Note: The npm ls vue-i18n command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Vue i18n, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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) .
