Alta video—1963: Sanitisation failure in vue-i18n could lead to DOM-XSS

Release Date

11th of November 2025.

Overview

A vulnerability was identified in Vue I18n, an internationalization plugin for Vue.js. The escapeParameterHtml: true option, intended to prevent HTML/script injection, failed to prevent the execution of certain tag-based payloads when interpolated values were inserted inside an HTML context using v-html. This vulnerability could lead to a DOM-based XSS vulnerability, even when using the escapeParameterHtml: true option, if a translation string included minor HTML and was rendered via v-html.
