Affected Products and Versions
All supported versions (10.x, and 12.x) of Node.js are vulnerable.
Through the command-line Cloud Foundry client run the following command:
cf ssh <appname> -c “cat app/logs/staging_task.log” | grep “Installing node”
-----> Installing node 10.21.1
Alternatively, through the command-line Cloud Foundry client run the following command:
$ cf ssh <appname> -c “cat app/logs/staging_task.log” | grep “IBM SDK for Node.js”
-----> IBM SDK for Node.js Buildpack v4.5-20201130-1530
If the Buildpack version is not at least v4.5 your application may be vulnerable.
Remediation/Fixes
The fixes for these vulnerabilities are included in Node.js v10.22.1 and subsequent releases.
The fixes for these vulnerabilities are included in Node.js v12.18.4 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": "10.*"
},
or
"engines": {
"node": "12.*"
},
You will then need to restage (or re-push) your application using the IBM SDK for Node.js Buildpack v4.5.
