About Node.js 21
Node.js 21 reached end of life on June 1, 2024, roughly 1 year ago. Since then, no security patches have been issued. If you are still running Node.js 21, you should treat upgrading as a high-priority item. Any CVEs discovered against this version will not be fixed upstream.
The recommended upgrade target is Node.js 24 LTS. You are 3 major versions behind, so review the changelog for each version in between to catch any breaking changes. A staged upgrade through each major version is often safer than jumping directly.
