How a Malicious JSON Crashes Node.js Servers via Async Hooks and the New Fix

The recent Node.js security release patches eight vulnerabilities, most notably a stack‑overflow bug triggered by deep recursive promises when async_hooks is enabled, which allows a crafted JSON payload to terminate the process, and the fix modifies TryCatchScope to re‑throw stack‑overflow errors instead of exiting.

Full-Link Tracing in Node.js Applications: Async Hooks and Zone-Context Design

The article details a full‑link tracing system for Node.js that leverages experimental async_hooks to monitor asynchronous resource lifecycles, builds an invoke‑tree to map parent‑child relationships, implements garbage collection, and provides a ZoneContext API for propagating custom tracing data across async call chains.
