External endpoint support for network graph

The StackRox Kubernetes Security Platform version adds support for external network endpoints in the network graph See the network graph topic to learn more about viewing and configuring external endpoints in the network graph.

Important bug fixes

  • ROX-5597: Previously, if you were monitoring Google’s Container-Optimized OS with Collector by using eBPF probes, sometimes the OS reported high CPU usage. We’ve optimized the Collector image to reduce CPU usage.
  • ROX-5758: Previously, Scanner didn’t mark some ASP.Net Core CVEs as fixable (only for patch releases) because the corresponding NVD database didn’t report fixes for those CVEs. We’ve updated Scanner, and it now reports fixable ASP.Net Core CVEs.

Resolved in version

Release date: Dec 7, 2020

  • ROX-5984: We’ve fixed an issue where unconfigurable options were visible when configuring the syslog integration.
  • ROX-5988: We’ve fixed an issue where viewing image components caused UI errors under certain conditions.
  • ROX-6070: Previously, when integrating with some OpenID Connect (OIDC) Identity Providers, the Test Login option would report connection errors. We’ve fixed this issue.

Important system changes

StackRox portal

We’ve removed the redundant option to filter risks by priority from the Risk view.


Scanner now identifies vulnerabilities in the latest Ubuntu version 20.10 images, and distroless Docker images.

Policy criteria

We’ve added new policy criteria called Container Name that evaluate policy against the provided container name.
