How to Fix CVE-2017-16014

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

http-proxy fixed: 0.7.0
npm install http-proxy@0.7.0
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 http-proxy

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-16014, inspect your project dependencies using npm:

npm ls http-proxy

Analyze the terminal output to locate any version of Http proxy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.

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