You can also find this file through the command-line Cloud Foundry client by running the following command:

cf ssh <appname> -c cat staging_info.yml

Look for the following lines:
{"detected_buildpack":"SDK for Node.js(TM) (ibm-node.js-xxx,","start_command":"./vendor/initial_startup.rb"}

If the Node.js engine version is not at least v6.14.0 or v8.11.1 your application may be vulnerable.


The fixes for these vulnerabilities are included in IBM SDK for Node.js v6.140 and subsequent releases.
The fixes for these vulnerabilities are included in IBM SDK for Node.js v8.11.1 and subsequent releases.

To upgrade to the latest version of the Node.js runtime, please specify the latest Node.js runtime in your package.json file for your application:

"engines": {
"node": ">=6.14.0"
"engines": {
"node": ">=8.11.1"

You will then need to restage (or re-push) your application using the IBM SDK for Node.js Buildpack v3.21.
