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...

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...

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...
