CVE-2026-47141
A flaw was found in vm2, an open-source virtual machine VM sandbox for Node.js. Prior to version 3.11.4, NodeVM, a component of vm2, improperly exposed certain process-wide observability builtins, such as diagnosticschannel, asynchooks, and perfhooks. These builtins, which are designed for...
CVE-2026-47141
vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The diagnosticschannel, asynchooks, and perfhooks builtins are not blocked by the dangerous builtin denylist. These modules...

CVE-2026-47141
CVE-2026-47141 affects vm2 NodeVM where diagnostics_channel, async_hooks, and perf_hooks observability builtins were exposed to sandboxed code before patching in vm2 3.11.4. These process‑wide modules can leak host data (e.g., HTTP headers, AsyncResource state, performance entries) into the sandb...

GHSA-9G8X-92Q2-P28F NodeVM observability builtins leak host process and HTTP request data
Summary NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The following builtins are not blocked by the dangerous builtin denylist: text diagnosticschannel asynchooks perfhooks These modules are process-wide, not sandbox-local. Sandboxed code c...
Incomplete List of Disallowed Inputs
Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the NodeVM builtin allowlist in lib/builtin.js. An attacker can read host-process state by supplying a sandb...

nodejs: Nodejs denial of service
A stack overflow flaw has been discovered in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when asynchooks.createHook is enabled. Instead of reaching process.on'uncaughtException', the process terminates, making the crash unrecoverable. Applications tha...

Denial Of Service (DoS)
Node.js is vulnerable to Denial of Service DoS. The vulnerability is due to improper error handling when asynchooks.createHook is enabled, where "Maximum call stack size exceeded" errors become uncatchable and terminate the process instead of reaching uncaughtException, allowing attackers to...
