Short explanation

CVE-2026-118256 in Vue I18n occurs because enabling escapeParameter, referred to as escapeParameterHtml in the Legacy API, fails to escape named interpolation values when translation calls supply both list and named values simultaneously.

Why does it matter?

This vulnerability allows attackers to inject attacker-controlled markup including phishing links, forms, and layout changes into applications rendering translations as HTML.

What should be done?

  • Update to fixed versions
  • Follow vendor advisory recommendations
Chain of evidence and sources2 verified claims

escapeParameter etkinleştirildiğinde, aynı çeviri çağrısı hem liste hem de isimlendirilmiş değerler sağladığında isimlendirilmiş enterpolasyon değerleri kaçış işlemine tabi tutulmaz.

Zafiyet escapeParams() fonksiyonunun yalnızca liste dalını işlemesinden kaynaklanır.

Show the technical text from the sources

Vue I18n is the internationalization plugin for Vue.js. From 9.0.0-beta.5 until 11.4.14 and 12.0.0-alpha.5, enabling escapeParameter, called escapeParameterHtml in the Legacy API, does not escape named interpolation values when the same translation call supplies both list and named values because escapeParams() processes only the list branch. Applications that render translations as HTML and pass untrusted named values with a list can insert attacker-controlled markup, including phishing links, forms, and layout changes, and can permit script execution when combined with the srcdoc sanitizer bypass or on releases without the sanitizer. This issue is fixed in versions 11.4.14 and 12.0.0-alpha.5.
