      "value": "Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. In versions prior to 4.12.28, the built-in clean-html sanitizer can be bypassed by a MathML/<style> carrier that hides a dangerous element from the sanitizer's element walk, so a no-interaction event handler survives into the editor value, potentially causing Mutation XSS. When an application supplies attacker-influenced HTML to the editor's value-set or insertion paths, the sanitized output still contains a live <img ... onload=...> (or another non-onerror handler such as onfocus). A consumer that renders that output (element.innerHTML = editor.value) executes the handler with no user interaction. This issue has been fixed in version 4.12.28."

      "value": "Jodit Editor es un editor WYSIWYG con capacidades de edición de archivos e imágenes, escrito en TypeScript puro. En versiones anteriores a la 4.12.28, el saneador clean-html incorporado puede ser eludido por un portador MathML/[style] que oculta un elemento peligroso del recorrido de elementos del saneador, por lo que un gestor de eventos sin interacción sobrevive en el valor del editor, lo que podría causar XSS por mutación. Cuando una aplicación proporciona HTML influenciado por el atacante a las rutas de establecimiento de valor o inserción del editor, la salida saneada aún contiene un <img ... onload_disabled=...> activo (o cualquier otro gestor que no sea onerror, como onfocus). Un consumidor que renderiza esa salida (element.innerHTML = editor.value) ejecuta el gestor sin interacción del usuario. Este problema ha sido solucionado en la versión 4.12.28."
