CVE-2025-59466
January 20, 2026
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.
