| शीर्षक | Bytedesk <=1.3.9 Unrestricted Upload of File with Dangerous Type (CWE-434) |
|---|
| विवरण | The authenticated endpoint POST /api/v1/upload/file accepts SVG files with embedded <script> tags. Although isAllowedFileType() permits image/svg+xml, the server stores the file without sanitizing its contents. An attacker with a valid token uploads a malicious SVG containing JavaScript; the returned fileUrl serves the file directly. When a victim visits the URL, the browser executes the script, resulting in Stored XSS. |
