| Titolo | Bytedesk <=1.3.9 Unrestricted Upload of File with Dangerous Type (CWE-434) |
|---|
| Descrizione | The authenticated file upload endpoint routes SVG files through UploadWatermarkService.addWatermarkToFile(), which writes the file to disk without stripping embedded JavaScript. The POC uploads an SVG containing <script>alert(...)></script> to POST /api/v1/upload/file; the server returns HTTP 200 and a public URL. Visiting the URL triggers Stored XSS, bypassing watermark processing without sanitization. |
