CVE-2025-57786Public exploitNetwork attack vector

Browser code execution via unsanitized user 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. Pacs/notifynewstudy.php copies the attacker-controlled user query parameter directly into an HTML error response without sanitization or output encoding. Exploitation requires a valid PACS session and a user to follow the crafted link, enabling script execution in that user's browser context.
