Summary
  • (es) PHPSpreadsheet es una librería PHP pura para leer y escribir archivos de hojas de cálculo. En las versiones afectadas, `\PhpOffice\PhpSpreadsheet\Writer\Html` no desinfecta la información de estilo de las hojas de cálculo, como los nombres de las fuentes, lo que permite a un atacante inyectar JavaScript arbitrario en la página. Como resultado, un atacante puede usar una hoja de cálculo manipulada para apoderarse por completo de la sesión de un usuario que visualiza archivos de hojas de cálculo como HTML. Este problema se ha solucionado en la versión 2.1.0. Se recomienda a todos los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
