CVE-2026-35608

QuickDrop is an easy-to-use file sharing application. Prior to 1.5.3, a stored XSS vulnerability exists in the file preview endpoint. 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.
