Arbitrary Code Injection

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 Arbitrary Code Injection despite the recently introduced neutralizeArraySpeciesBatch helper in lib/bridge.js. An attacker can execute arbitrary code ...

NPM: vm2 has sandbox breakout via `neutralizeArraySpeciesBatch`

PT-2026-39191

Name of the Vulnerable Software and Affected Versions VM2 affected versions not specified Description A sandbox breakout allows attackers to execute arbitrary commands on the host system. The issue occurs because the neutralizeArraySpeciesBatch function interacts with objects from an external...

CVE-2026-26956

A flaw was found in vm2, an open-source sandbox for Node.js. An attacker can exploit this vulnerability by running malicious code within the VM.run function, allowing them to escape the sandbox and gain access to the host process. This can lead to arbitrary code execution on the host system,...

Improper Isolation or Compartmentalization

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Improper Isolation or Compartmentalization through the NodeVM constructor in lib/nodevm.js. An attacker can run host commands when th...

NPM: vm2 NodeVM `nesting: true` bypasses `require: false` allowing sandbox escape and arbitrary OS command execution

vm2 NodeVM `nesting: true` bypasses `require: false` allowing sandbox escape and arbitrary OS command execution

Summary When a NodeVM is created with nesting: true, sandbox code can unconditionally require'vm2' regardless of the outer VM's require configuration — including require: false. With access to vm2, the sandbox constructs a new inner NodeVM with its own unrestricted require settings and executes...
