CVE-2023-25841Network attack vector

Browser script execution via stored feature content

Published Jul 21, 2023 · Updated Apr 10, 2025

Stored XSS in Esri ArcGIS Server 11.1 and earlier allows remote attackers to execute JavaScript in a victim's browser via crafted content. An anonymously accessible Feature Service with edit capabilities accepts attacker-controlled content that ArcGIS later renders without sufficient output neutralization. Anonymous editing must be enabled, and a victim must click the stored content; execution is confined to the victim's browser context.
