Attacker-supplied sandbox code needs no auth (PR:N) but exploitation depends on a non-default builtin/child_process allowance (AC:H); sandbox escape to host is S:C with full C/I/A:H.

vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability where the DANGEROUS_BUILTINS denylist omits child_process despite blocking other host-spawning modules. Attackers can require child_process and execute arbitrary commands on the host system when NodeVM is configured with builtin:['*'] or explicit child_process allowance.

AnalysisAI
Sandbox escape in vm2 NodeVM before 3.12.1 allows unauthenticated remote attackers to execute arbitrary commands on the host, but only when the application has been configured to allow child_process via builtin:['*'] or an explicit allowlist entry. Exploitation requires the host application to run untrusted JavaScript inside a NodeVM instance and to have this misconfiguration; default configurations that do not allow child_process are not vulnerable. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the host application to have already run untrusted/attacker-controlled JavaScript inside a vm2 NodeVM instance AND to have configured that instance with builtin:['*'] (wildcard builtin allowance) or an explicit child_process entry in the allowed builtins. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N with VC/VI/VA/SC/SI/SA all High = 10.0) frames this as maximum-severity unauthenticated remote code execution, and mechanically a sandbox escape that yields arbitrary host command execution does warrant near-top scores. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade to vm2 3.12.1 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Node.js applications and dependencies that embed vm2, and identify any NodeVM instances configured with builtin:['*'] or explicit child_process allowlist entries; if such misconfigurations exist, remove child_process from allowed builtins or disable the affected sandbox until remediation. …
