      "value": "Wekan is open source kanban built with Meteor. From 8.72 until 10.23, addBoardHTMLToZip() in client/lib/exportHTML.js read a card title and body through textContent, which decoded entity-encoded markup, and then interpolated titleText and allText into content.innerHTML in the exported index.html. A board member could store an entity-encoded event-handler payload in a card title that remained inert on the live board but was reparsed and executed when a recipient clicked the card in the downloaded HTML export, allowing the script to read and transmit all board data contained in that export, including content added after the attacker's membership was removed. Version 10.23 builds the modal with DOM nodes and assigns untrusted values through textContent. This issue is fixed in version 10.23."

      "value": "Wekan es un kanban de código abierto construido con Meteor. Desde la 8.72 hasta la 10.23, addBoardHTMLToZip() en cliente/lib/exportHTML.js leía un título y cuerpo de tarjeta a través de textContent, que decodificaba el marcado codificado por entidades, y luego interpolaba titleText y allText en content.innerHTML en el index.html exportado. Un miembro del tablero podía almacenar una carga útil de gestor de eventos codificada por entidades en el título de una tarjeta que permanecía inerte en el tablero en vivo, pero era reanalizada y ejecutada cuando un destinatario hacía clic en la tarjeta en la exportación HTML descargada, permitiendo que el script leyera y transmitiera todos los datos del tablero contenidos en esa exportación, incluyendo contenido añadido después de que la membresía del atacante fuera eliminada. La versión 10.23 construye el modal con nodos DOM y asigna valores no confiables a través de textContent. Este problema está solucionado en la versión 10.23."
