TL;DR: Static SBOMs cannot show which dependencies are actually executed, exposed, or exploitable across containers, APIs, pipelines, and AI-assisted development, according to OXSecurity. Execution lineage turns component lists into a risk view that can guide supply-chain decisions.
Editorial analysis by NHI Mgmt Group, based on content published by OXSecurity: “SBOM Security in 2026: Why Inventory Alone No Longer Reduces Risk”.
Key questions
Q: Why do build-time inventories fail to control software supply chain risk?
A: Because the risk emerges after the build succeeds.
Q: How should security teams decide which dependency updates to prioritise first?
A: Start with the vulnerabilities that affect reachable, internet-facing, or business-critical code paths, then move down by exploitability and blast radius.
Q: What breaks when SBOMs are used without execution lineage?
A: Static SBOMs break down when teams need to decide whether a dependency is actually reachable, executed, or exposed.
Practitioner guidance
- Correlate SBOMs with runtime exposure Link dependency inventories to deployment state, API reachability, and runtime usage so you can separate present-from-used components from merely listed ones.
- Map dependencies to execution lineage Track how each dependency enters through source, build, artifact, and container stages so the team can see where risk is introduced and propagated.
- Prioritise reachable components over inventory volume Use reachability, public exposure, and privilege context to rank remediation, instead of treating every vulnerable package as equally urgent.
Bottom line: SBOMs are useful for inventory, but they do not by themselves show which dependencies are executed, exposed, or exploitable.

Static inventories are not a control. SBOMs provide visibility into software composition, but visibility alone cannot tell teams whether a dependency is reachable, executed, or exposed in production. That makes component lists useful for audit evidence but incomplete for operational governance. Practitioners should treat inventory as an input to control decisions, not the control itself.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- 59% of compromised machines in a major 2025 supply chain attack were CI/CD runners rather than personal workstations, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: Should SBOM governance include CI/CD and runtime controls?
A: Yes. SBOM governance only becomes operational when CI/CD permissions, deployment context, and runtime behaviour are part of the same control model. Otherwise, teams know what was built but not what can actually be used or attacked in production.
