CVE-2023-6551 (GCVE-0-2023-6551)

Vulnerability from cvelistv5 – Published: 2024-01-04 16:04 – Updated: 2025-06-03 14:42
VLAI?
Title
Stored XSS in class.upload.php
Summary
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.
