found 21 high severity vulnerabilities in 917686 scanned packages 21 vulnerabilities require manual review. See the full report for details.

npm audit:

Package https-proxy-agent

Patched in >=2.2.3

Dependency of npm

Path npm > libnpm > npm-registry-fetch > make-fetch-happen >

High Machine-In-The-Middle

Package https-proxy-agent

Patched in >=2.2.3

Here are all of the relevant files in my project directory:
