There is a Cross‑Site Scripting (XSS) vulnerability in Esri ArcGIS Enterprise Sites versions 10.9 and below that may allow a remote, authenticated attacker to create a crafted link which, when clicked by a victim, could result in the execution of arbitrary JavaScript code in the target’s browser. Exploitation requires high‑privileged authenticated access. Successful exploitation may allow the attacker to access sensitive session data, manipulate trusted content, and disrupt normal application functionality, resulting in a high impact to confidentiality, integrity, and availability.
