npm install highcharts-export-server@2.1.0
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 highcharts-export-server

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-hfwx-c7q6-g54c, inspect your project dependencies using npm:

npm ls highcharts-export-server

Note: The npm ls highcharts-export-server 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-552: Files or Directories Accessible to External Parties, where the product makes files or directories accessible to unauthorized actors, even though they should not be. In Highcharts export server, 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

### Impact The vulnerability allows for reading and outputting files served by other services on the internal network in which the export server is hosted. If the export server is exposed to the internet, this potentially allows a malicious user to gain read access to internal web-resources. The impact is limited to internal services that serve content via. HTTP(S), and requires the attacker to know internal hostnames/IP addresses. The previous versions have been marked as deprecated on NPM. ### Patches Version 2.1.0 released alongside this security advisory addresses the issue. **Please note that this release is not backwards compatible out of the box. See the [changelog](https://github.com/highcharts/node-export-server/blob/master/CHANGELOG.md) for details.** Additionally, it's also recommended to upgrade to the latest version of Highcharts to get the added input sanitation implemented in version 9.0 and later. ### Workarounds There are no known workarounds to the issue - an upgrade to version 2.1.0 is required. ### For more information If you have any questions or comments about this advisory: * Open an issue in [the export server issue tracker](https://github.com/highcharts/node-export-server/issues) * Email us at [security@highsoft.com](mailto:security@highsoft.com)
