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.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-HFWX-C7Q6-G54C? GHSA-HFWX-C7Q6-G54C is a high-severity security vulnerability in highcharts-export-server (npm), affecting versions <= 2.0.30. It is fixed in 2.1.0.
- Which versions of highcharts-export-server are affected by GHSA-HFWX-C7Q6-G54C? highcharts-export-server (npm) versions <= 2.0.30 is affected.
- Is there a fix for GHSA-HFWX-C7Q6-G54C? Yes. GHSA-HFWX-C7Q6-G54C is fixed in 2.1.0. Upgrade to this version or later.
- Is GHSA-HFWX-C7Q6-G54C exploitable, and should I be worried? Whether GHSA-HFWX-C7Q6-G54C is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-HFWX-C7Q6-G54C is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
