Node.js security: lessons from the Node.js Security Working Group in triaging vulnerabilities

The article analyzes a reported server-side JavaScript code injection in Fastify's JSON schema handling: a PoC showed a reverse shell when untrusted JSON schema is parsed, but Fastify and its fast-json-stringify component are designed to treat schema input as trusted and to avoid dynamic parsing, so maintainers concluded this is not a framework vulnerability; the piece highlights triage challenges in assigning vulnerability scope and responsibility between libraries and application code.
