MEDIUM
The severity is rated MEDIUM because the issue lies in the misinterpretation of security scan results rather than an inherent vulnerability. However, this can lead to real risks being ignored due to a high noise level from theoretical vulnerabilities.

The post highlights a common issue with Kubernetes security scanning where the severity of findings does not account for workload context and exposure. Security scans may flag issues such as privileged containers, but without considering whether these workloads are externally facing or handle sensitive data, the findings can be misleading. This results in engineers potentially overlooking critical risks if they treat all scan alerts equally, focusing more on theoretical vulnerabilities than real-world exposures. The post seeks advice from others on how to integrate workload exposure and blast radius context into their security scanning process for a more accurate risk assessment.

Affected Systems
  • Kubernetes clusters
Affected Versions: All versions
Remediation
  • Implement a custom scoring system for security findings that considers the exposure and criticality of each workload.
  • Review and prioritize findings based on whether workloads are externally facing or handle sensitive data.
  • Update your Kubernetes security scanning tools to support context-aware severity adjustments if available.
Stack Impact

This issue impacts any homelab setup using Kubernetes for production or development environments, where the true risk of vulnerabilities is not aligned with their actual exposure and importance within the cluster. The impact can be minimized by carefully reviewing each finding in the context of its workload.
