CVE-2025-57875Network attack vector

Administrator-authenticated script execution via reflected input

Published Sep 29, 2025 · Updated Sep 29, 2025

Reflected XSS in Esri Portal for ArcGIS 10.9.1 through 11.4 allows remote authenticated users to execute JavaScript in a browser. Esri has not published the affected endpoint or the exact operation that reflects the crafted string into browser-rendered output without neutralization. Exploitation requires administrative access and user interaction; successful injection runs script in the viewing user's browser context but does not interrupt the service.
