There is a stored Cross‑Site Scripting (XSS) vulnerability in Esri Portal for ArcGIS Sites versions 11.1 and below that may allow a remote, authenticated attacker with high‑privileged access to create a crafted link that is persisted within the site configuration. When accessed by a victim, the stored payload may execute arbitrary JavaScript code in the victim’s browser. Successful exploitation could allow the attacker to access sensitive user data and session information, alter trusted site content and user actions, and disrupt normal site functionality, resulting in a high impact to confidentiality, integrity, and availability.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.4, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from esri organizations running these solutions should prioritize assessment and patching.
Reported in 2023, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For esri's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
