CVE-2023-6551

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2023-6551
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.
