How to Fix CVE-2023-48094

To remediate this vulnerability, upgrade all affected Cesium dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

cesium fixed: Latest secure release 
npm install cesium@Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls cesium

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-48094, inspect your project dependencies using npm:

npm ls cesium

Analyze the terminal output to locate any version of Cesium in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls cesium command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Cesium, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A cross-site scripting (XSS) vulnerability in CesiumJS v1.111 allows attackers to execute arbitrary code in the context of the victim's browser via sending a crafted payload to /container_files/public_html/doc/index.html. NOTE: the vendor’s position is that Apps/Sandcastle/standalone.html is part of the CesiumGS/cesium GitHub repository, but is demo code that is not part of the CesiumJS JavaScript library product.'
