CVEID:CVE-2020-8116
**DESCRIPTION:**Node.js dot-prop could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/175850 for the current score.

Affected Products and Versions

Remediation/Fixes

To remove the security vulnerability exposure, use the new nodejs and nodejs-express stacks in IBM Cloud Pak for Applications, change the stack hub repository for your kabanero resource. For example, “oc edit kabanero kabanero” and change the url for the repsitory:

apiVersion: kabanero.io/v1alpha2
kind: Kabanero
metadata:
name: kabanero
namespace: kabanero
spec:
…
repositories:
- gitRelease: {}
https:
url: <https://github.com/icp4apps/stack-hub/releases/download/0.22.1/icp4apps-stack-hub-index.yaml&gt;

This configuration change will pick up the new nodejs and nodejs-express stacks located at: <https://github.com/kabanero-io/collections/releases/tag/0.10.4&gt;
