Summary

QuickDrop before version 1.5.3 has a stored XSS vulnerability in the file preview endpoint. The application allows SVG file uploads via /api/file/upload-chunk, and a malicious SVG with JavaScript payload executes in the application's domain context when previewed. The vulnerability is fixed in 1.5.3.

Risk Assessment

Stored XSS can allow an attacker to execute arbitrary JavaScript in the victim's browser, steal sessions or credentials. This may lead to account takeover or further attacks within the application context.

Recommendation

Update QuickDrop to version 1.5.3 or later. Additionally, implement validation and sanitization of uploaded SVG files and consider blocking SVG files in preview.
