Kubernetes security context based vulnerability exploitability filtering
Problem
Traditional vulnerability scanners flag vulnerabilities that are mitigated by Kubernetes security contexts (e.g., readOnlyRootFilesystem, dropped capabilities), creating a high volume of false positives. There is a need for a tool that integrates security context analysis and ML prediction to distinguish exploitable vulnerabilities and reduce noise.
Pain points
- Kubernetes security contexts cause a high volume of false positives in vulnerability scanning
Questions to verify
- Does your current vulnerability scanning pipeline already incorporate security context information?
- Would you be interested in integrating such filtering capabilities into your existing CI/CD security pipeline?
- What level of accuracy and explainability do you expect from the model's predictions?

vex8s is an open source tool that analyzes Kubernetes workloads and generates VEX documents based on their SecurityContext.The idea is to distinguish vulnerabilities that are actually exploitable in a given deployment from those mitigated by Kubernetes security settings (for example, readOnlyRootFilesystem, dropped capabilities, non-root users, and read-only volume mounts).vex8s embeds a ML model trained on CVE data to predict vulnerability classes, then combines those predictions with the workload's security configuration to determine whether a vulnerability can be mitigated.I'm particularly interested in feedback on the decision logic and on whether this approach could be useful as part of a vulnerability scanning pipeline.GitHub: https://github.com/alegrey91/vex8s
