CVE-2025-55071Public exploitNetwork attack vector

Pre-auth script execution via unsanitized name parameter

Published Jan 20, 2026 · Updated Jan 20, 2026

Reflected XSS in MedDream PACS Premium 7.3.6.870 allows remote attackers to execute JavaScript through a crafted modifyAnonymize URL. The Pacs/modifyAnonymize.php script URL-decodes the name query parameter and prints it into headings and a hidden input without sanitization. Exploitation requires a user to open the crafted URL, after which the script runs in the PACS web interface's browser context and can read or alter data available to that session.
