Description

We have identified a bug in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when `async_hooks.createHook()` is enabled. Instead of reaching `process.on('uncaughtException')`, the process terminates, making the crash unrecoverable. Applications that rely on `AsyncLocalStorage` (v22, v20) or `async_hooks.createHook()` (v24, v22, v20) become vulnerable to denial-of-service crashes triggered by deep recursion under specific conditions.

Affected configurations

• nodejs node.js (>= 20.0.0 < 20.20.0) • nodejs node.js (>= 22.0.0 < 22.22.0) • nodejs node.js (>= 24.0.0 < 24.13.0) • nodejs node.js (>= 25.0.0 < 25.3.0)
