Description

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(&#39;vm2&#39;) regardless of the outer VM&#39;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.
