CVE-2023-1746Network attack vector

Script execution via file upload handler

Published Mar 30, 2023 · Updated Nov 22, 2024

Cross-site scripting in Dreamer CMS 3.5.0 and earlier allows remote authenticated users to execute scripts through the file upload handler. Public records identify neither the affected function nor how uploaded content reaches an executable page context, leaving the precise validation failure undisclosed. Exploitation requires low-privilege access and a victim to view the crafted content, enabling script execution in that viewer's browser.
