CVE-2025-27145

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.

Summary
  • (es) copyparty, un servidor de archivos portátil, tiene una vulnerabilidad de Cross-Site Scripting basada en DOM en versiones anteriores a la 1.16.15. La vulnerabilidad se considera de bajo riesgo. Al entregarle a alguien un archivo con un nombre malicioso y luego engañarlo para que lo arrastre a la interfaz web de copyparty, un atacante podría ejecutar javascript arbitrario con los mismos privilegios que ese usuario. Por ejemplo, esto podría dar acceso de lectura no deseado a archivos propiedad de ese usuario. El error se activa con la acción de arrastrar y soltar en sí; no es necesario iniciar realmente la carga. El archivo debe estar vacío (cero bytes). Tenga en cuenta que, como servidor web de propósito general, es posible cargar intencionalmente archivos HTML con javascript arbitrario en las etiquetas `
