    Improper Encoding or Escaping of Output

    @intlify/core-base is a @intlify/core-base

    Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the sanitizeTranslatedHtml function in packages/shared/src/sanitize.ts, which fails to neutralize srcdoc attributes in translation messages. An attacker who controls translation message content can inject a srcdoc attribute on an <iframe> element; the browser entity-decodes the attribute value and parses it as a full HTML document in the same origin as the page, allowing arbitrary script execution. The existing sanitizer neutralized on* event handlers but did not account for the secondary HTML parsing context that srcdoc introduces, leaving that vector unblocked.

    How to fix Improper Encoding or Escaping of Output?

    Upgrade @intlify/core-base to version 12.0.0-alpha.5, 11.4.14 or higher.

    Improper Encoding or Escaping of Output

    @intlify/core-base is a @intlify/core-base

    Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the escapeParams function in packages/core-base/src/translate.ts, when a translation call passes both list and named interpolation values simultaneously. The original logic used else if to escape named values, meaning that when a list argument is also present, named values are never passed through escapeHtml. An attacker who controls a named interpolation value can inject unescaped HTML into the rendered output, enabling a cross-site scripting attack.

    Note: This is only exploitable when the escapeParameter option is explicitly set to true.

    How to fix Improper Encoding or Escaping of Output?

    Upgrade @intlify/core-base to version 12.0.0-alpha.5, 11.4.14 or higher.
