Technical details
A stored cross-site scripting (XSS) vulnerability exists in Esri ArcGIS Server 11.4 and earlier on Windows and Linux platforms. The vulnerability allows remote unauthenticated attackers to upload or store files containing malicious JavaScript code that persists on the server. When victims access affected areas of the application, the injected code executes in their browser context with their privileges. The issue affects certain server configurations and requires no user authentication to exploit. A patch has been made available as part of the ArcGIS Server 2025 Update 2 security patch.
