Endor Labs explains VEX (Vulnerability Exploitability eXchange), the CISA-backed machine-readable format that lets software producers assert whether a vulnerability in a component actually affects their product, complementing SBOMs which only list components and versions. It walks through how VEX documents annotate exploitability (e.g., unreachable code), and describes how Endor Labs automates this by building a dependency callgraph via static analysis to determine reachability and auto-generate SBOM/VEX documents.
