Stored script execution in victim browsers

Published Apr 18, 2023 · Updated Feb 6, 2025

Stored cross-site scripting in Dreamer CMS 3.0.1 allows remote authenticated users to execute script in another user's browser. The sole upstream issue linked by the CVE record is no longer available, so the affected input, storage path, and missing output-encoding operation are not publicly documented. Exploitation requires low-privileged access and user interaction; successful payload rendering can expose or alter data in the victim's browser context.
