      "value": "copyparty, a portable file server, has a DOM-based cross-site scripting vulnerability in versions prior to 1.16.15. The vulnerability is considered low-risk. By handing someone a maliciously-named file, and then tricking them into dragging the file into copyparty's Web-UI, an attacker could execute arbitrary javascript with the same privileges as that user. For example, this could give unintended read-access to files owned by that user. The bug is triggered by the drag-drop action itself; it is not necessary to actually initiate the upload. The file must be empty (zero bytes). Note that, as a general-purpose webserver, it is intentionally possible to upload HTML-files with arbitrary javascript in `<script>` tags, which will execute when the file is opened. The difference is that this vulnerability would trigger execution of javascript during the act of uploading, and not when the uploaded file was opened. Version 1.16.15 contains a fix."

La vulnerabilidad se considera de bajo riesgo. Al entregarle a alguien un archivo con un nombre malicioso y luego enga\u00f1arlo para que lo arrastre a la interfaz web de copyparty, un atacante podr\u00eda ejecutar javascript arbitrario con los mismos privilegios que ese usuario. Por ejemplo, esto podr\u00eda dar acceso de lectura no deseado a archivos propiedad de ese usuario. El error se activa con la acci\u00f3n de arrastrar y soltar en s\u00ed; no es necesario iniciar realmente la carga. El archivo debe estar vac\u00edo (cero bytes). Tenga en cuenta que, como servidor web de prop\u00f3sito general, es posible cargar intencionalmente archivos HTML con javascript arbitrario en las etiquetas `"
