vue-i18n is an internationalization plugin for Vue.js. In affected versions vue-i18n can be passed locale messages to `createI18n` or `useI18n`. When locale message ASTs are generated in development mode there is a possibility of Cross-site Scripting attack. This issue has been addressed in versions 9.14.2, and 10.0.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.
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.
