The application allows SVG files to be uploaded via the /api/file/upload-chunk endpoint. An attacker can upload a specially crafted SVG file containing a JavaScript payload. When any user views the file preview, the script executes in the context of the application's domain. This vulnerability is fixed in 1.5.3.

Summary		(es) QuickDrop es una aplicación de intercambio de archivos fácil de usar. Antes de la versión 1.5.3, existe una vulnerabilidad XSS almacenada en el endpoint de previsualización de archivos. La aplicación permite la carga de archivos SVG a través del endpoint /api/file/upload-chunk. Un atacante puede cargar un archivo SVG especialmente diseñado que contiene una carga útil de JavaScript. Cuando cualquier usuario visualiza la previsualización del archivo, el script se ejecuta en el contexto del dominio de la aplicación. Esta vulnerabilidad está corregida en la versión 1.5.3.
