Outdated Node.js Versions a Problem

OpenJS is launching the Node.js LTS Upgrade and Modernization program to help enterprises move off outdated Node.js versions. Roughly two-thirds of Node.js users are running outdated or unsupported versions, creating security and operational risks. These outdated versions no longer receive security updates, leaving applications vulnerable to exploits. A remote attacker can exploit these vulnerabilities to trigger denial of service or bypass security restrictions. Some industry audits forbid unmaintained runtimes. The Node.js team issued a CVE for all End-of-Life (EOL) releases to raise awareness of the security risks associated with using outdated Node.js versions. Node.js v16, for example, was downloaded 11 million times per month even after it was EOL. The LTS Upgrade program connects organizations with experienced service providers to handle upgrades safely. Approved partners assess versions and dependencies, manage upgrades to supported releases, and offer temporary security support. NodeSource is the inaugural partner in the program. If upgrading isn't immediately possible, commercial support options exist. HeroDevs, for instance, provides Never-Ending Support (NES) for EOL Node.js versions, including security patches and compliance assistance. JavaScript performance degrades non-linearly as applications grow, making it harder to predict, measure, and fix performance issues. Teams should treat performance as a core requirement, profiling regularly and testing on low-end devices. Using code splitting and lazy loading can reduce initial load times. Caching API responses in memory or IndexedDB can also save bandwidth and user time.
