CVE-2026-25200 is an HTML file upload vulnerability in Samsung MagicInfo9 (MagicINFO 9) Server affecting versions prior to 21.1090.1. The application permits uploading HTML content in a way that results in stored cross-site scripting (XSS): attacker-supplied script embedded in the uploaded HTML is stored server-side and later executed in an administrator’s browser when the content is viewed via the MagicINFO management console. The supporting content characterizes the condition as an unauthenticated HTML upload leading to stored XSS and potential account takeover.
