CVE-2025-57881Public exploitNetwork attack vector

Authenticated script execution via unsanitized server parameter

Published Jan 20, 2026 · Updated Jan 20, 2026

Reflected XSS in MedDream PACS Premium 7.3.6.870 allows remote authenticated users to execute JavaScript through a crafted URL. The Pacs/modifyEmail.php script passes its server query parameter to an HTML error message without sanitization when the named server is absent from the database. Exploitation requires an authenticated victim to open the URL; the injected script then runs in that victim's browser session and can read or alter page-accessible data.
