Vm2_Project
Parameter Value
CVSS 9.1 (CRITICAL)
Affected Versions before 3.11.1
Fixed In 3.11.1
Type CWE-1100, CWE-284 (Improper Access Control)
Vendor Vm2_Project
Public PoC No

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.1, 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 arbitrary OS commands on the host.

Any application that runs untrusted code inside a NodeVM with nesting: true is fully compromised. This vulnerability is fixed in 3.11.1.
