Prior to 2.0.0, the Get Info workflow in app/core/src/main/resources/templates/security/get-info-on-pdf.html inserts untrusted PDF Title and Author metadata into the summary-text element with innerHTML, allowing a malicious PDF to execute stored cross-site scripting when a user clicks Get Info and to access browser-session data or modify page content. This issue is fixed in version 2.0.0."

Antes de la versión 2.0.0, el flujo de trabajo ’Get Info’ en app/core/src/main/resources/templates/security/get-info-on-pdf.html inserta metadatos no confiables de Título y Autor del PDF en el elemento ’summary-text’ con innerHTML, permitiendo que un PDF malicioso ejecute cross-site scripting almacenado cuando un usuario hace clic en ’Get Info’ y acceda a datos de la sesión del navegador o modifique el contenido de la página. Este problema está solucionado en la versión 2.0.0."
