CVE-2023-6551 · Stored XSS in class.upload.php

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
