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.\n\n## Affected\n\n- `vm2 < 3.11.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `vm2 3.11.1`","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
