Prior to version 3.11.4, NodeVM blocks several dangerous Node.js builtins such as module, worker_threads, cluster, vm, repl, and inspector. However, the denylist misses process and inspector/promises. Both can be used from sandboxed code to reach host-side execution primitives. This allows sandboxed code to bypass the intended builtin restrictions and execute code in the host process. This issue has been patched in version 3.11.4."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"patriksimek","product":"vm2","versions":[{"version":"< 3.11.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","baseScore":10.0,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":6.0}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-12T00:00:00+00:00","id":"CVE-2026-47140","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-693"}]}],"references":[{"url":"https://github.com/patriksimek/vm2/commit/a1ed47a98d1cc36cb48c0d566d55889688e0b59b","source":"security-advisories@github.com"},{"url":"https://github.com/patriksimek/vm2/releases/tag/v3.11.4","source":"security-advisories@github.com"},{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-rp36-8xq3-r6c4","source":"security-advisories@github.com"},{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-rp36-8xq3-r6c4","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
