If you ship a product that includes es-define-property, the Cyber Resilience Act expects you to know which components you ship, to follow their vulnerabilities and to exercise due diligence on third-party components (Annex I, Part II and Article 13). In practice: list es-define-property 1.0.1 in your SBOM with its package URL pkg:npm/[email protected], watch for new advisories, and keep the upstream security contact in your vulnerability handling process.
