title: Stored XSS in class.upload.php
description: As a simple library, class.upload.php does not perform an in-depth check on uploaded files, allowing a stored XSS vulnerability when the default configuration is used.
Developers must be aware of that fact and use extension whitelisting accompanied by forcing the server to always provide content-type based on the file extension.
The README has been updated to include these guidelines.
