European product liability law is being quietly but fundamentally rewritten. Software, AI systems and open source components move from the periphery into the legal core of what counts as a “product”, while cyber security and lifecycle management become part of the defect analysis. For management and engineering teams this means that software composition, open source usage and SBOM can no longer be treated as purely technical housekeeping; they are now part of the liability model.
This article outlines the key elements of the new regime, explains how software, AI and open source are treated, and shows why SBOM and the Cyber Resilience Act (CRA) will be central in practice.
