What is CVE-2016-10637?

CVE-2016-10637 is a high-severity security vulnerability in haxe-dev (npm), affecting versions <= 3.2.1. No fixed version is listed yet.

Which versions of haxe-dev are affected by CVE-2016-10637?

haxe-dev (npm) versions <= 3.2.1 is affected.

Is there a fix for CVE-2016-10637?

No fixed version is listed for CVE-2016-10637 yet. Monitor the advisory for updates and apply mitigations in the interim.

Is CVE-2016-10637 exploitable, and should I be worried?

Whether CVE-2016-10637 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 CVE-2016-10637 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.

Summary

Downloads Resources over HTTP in haxe-dev

Affected versions of haxe-dev insecurely download an executable over an unencrypted HTTP connection.

In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running haxe-dev.

Impact

Affected versions

haxe-dev (<= 3.2.1)

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.

Remediation advice

This package is actively maintained, yet after 2 years, the maintainer has not provided a patch for the vulnerability. This likely means that the maintainer has decided to accept the risk, and this vulnerability will never be patched.

Because of this, the best mitigation is currently to avoid using this package, using a different package if available.

Alternatively, the risk of exploitation can be reduced by ensuring that this package is not installed while connected to a public network. If the package is installed on a private network, the only people who can exploit this vulnerability are those who have compromised your network or those who have privileged access to your ISP, such as Nation State Actors or Rogue ISP Employees.
