CVE-2025-54862Network attack vector

Cookie theft via stored HTML injection

Published Aug 18, 2025 · Updated Aug 19, 2025

Stored cross-site scripting in Santesoft Sante PACS Server before 4.2.3 allows remote authenticated users to steal cookies via HTML injection. Public advisories identify the web portal as the injection and storage locus but do not disclose which field accepts the markup or how output encoding fails. A low-privileged web account and interaction by another portal user are required; injected content can redirect that user and expose the session cookie.
