CVE-2025-59466 (GCVE-0-2025-59466)

Vulnerability from cvelistv5 – Published: 2026-01-20 20:41 – Updated: 2026-01-20 20:41
VLAI?
Summary
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.
