Authenticated HTML injection in home application

Published Aug 15, 2022 · Updated Apr 10, 2025

HTML injection in Esri Portal for ArcGIS 10.8.1 and earlier allows remote authenticated users to inject HTML into the home application. Esri identifies the home application as the affected locus but has not disclosed which input reaches an HTML-rendering sink or what validation is missing. Exploitation requires an authenticated account and user interaction, with impact limited to information disclosure and content modification in another browser context.
