Other Information:

[4security]

The project discontinued. 9.8 CVE is very high severity (9.8 of 10) https://nvd.nist.gov/vuln/detail/CVE-2023-37466 and should be replaced by https://www.npmjs.com/package/isolated-vm

I don't know the Ionic codebase but vm2 is used to "run untrusted code in Node" should be optional part of a framework.

The ionic cli itself, mainly to download the starter templates when running ionic start, has to do http requests.

These requests are done using the superagent package.

In order for superagent to support proxies it uses the superagent-proxy package which has not been updated in the last 2 years (but may be getting another update soon just to address this issue, see https://github.com/TooTallNate/superagent-proxy/pull/50)

A proxy server can be configured either by manually specifying proxy parameter or by a proxy autoconfigure script (PAC).

A PAC is basically a Javascript script that computes the proxy parameters dynamically based on destination. PAC resolution is performed by the proxy-agent dependency by running the script in a sandboxed VM.

Older version of proxy-agent ultimately depend on the deprecated vm2 package to run such js code in a sandboxed environment, newer version don't.

So, if you are in a network with an autoconfigured proxy and run ionic start (or add Cordova integration through ionic integration add cordova) you are allowing the network administrator that publishes the proxy script to run arbitrary code on your machine thank to the vm2 bug.

If you are not using an autoconfigured proxy in your development computer, you are not at risk and may disregard the warning.

Is there a way to reduce dependencies? A PAC proxy is edge case for dev machine. Do you think about a kind of plugin / extension?

It is not so nice to have CVEs any projects because of exploitation chains.
