There is a stored Cross-site Scripting vulnerability in Esri Portal for ArcGIS Enterprise Web App Builder versions 10.8.1 – 10.9.1 that may allow a remote, authenticated attacker to create a crafted link which when clicked could potentially execute arbitrary JavaScript code in the victim’s browser. The privileges required to execute this attack are high. 

There is a difficult to exploit improper authentication issue in the Home application for Esri Portal for ArcGIS versions 10.8.1 through 11.2 on Windows and Linux, and ArcGIS Enterprise 11.1 and below on Kubernetes which, under unique circumstances, could potentially allow a remote, unauthenticated attacker to compromise the confidentiality, integrity, and availability of the software.

An information disclosure vulnerability in the ArcGIS Service Directory in Esri ArcGIS Enterprise versions 10.9.0 and below may allows a remote attacker to view hidden field names in feature layers. This issue may reveal field names, but not not disclose features.

A cross-site scripting (XSS) vulnerability in the Document Link of documents in ESRI Enterprise before 10.9 allows remote authenticated users to inject arbitrary JavaScript code via a malicious HTML attribute such as onerror (in the URL field of the Parameters tab).

In ArcGIS Enterprise 10.6.1, a crafted IFRAME element can be used to trigger a Cross Frame Scripting (XFS) attack through the EDIT MY PROFILE feature.
