Node.js patched a critical bug where AsyncLocalStorage could cause stack overflows to bypass error handlers and terminate production servers with exit code 7. The issue affected virtually every production Node.js app using async context tracking, including React Server Components, Next.js, and APM tools. Stack overflow errors would crash the entire server process instead of returning catchable RangeErrors. The fix was included in security releases for Node.js versions 20.20.0, 22.22.0, 24.13.0, and 25.3.0, though Node.js 24+ were less affected due to reimplemented AsyncLocalStorage.
