There is a reflected Cross‑Site Scripting (XSS) vulnerability in Esri Portal for ArcGIS versions 11.1 and 11.2 that may allow a remote, authenticated attacker with low‑privileged access to create a crafted link which, when clicked, could potentially execute arbitrary JavaScript code in the victim’s browser.
