The module is presented via a recursive read-only proxy, but its callable exports still execute with host-process authority. Sandboxed JavaScript can therefore call crypto.setEngine() with a filesystem path to an attacker-supplied native library (for example, one bundled in an untrusted plugin package already written to disk); OpenSSL asks the operating-system dynamic loader to load the file, and the library's constructor executes native code in the host process before engine-symbol validation rejects it. Exploitation requires only the crypto builtin and does not require fs, process, module, child_process, worker_threads, vm, or inspector access, resulting in a sandbox escape and arbitrary native code execution. Fixed in 3.11.7."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Process Control","cweId":"CWE-114","type":"CWE"}]}],"affected":[{"vendor":"patriksimek","product":"vm2","defaultStatus":"unaffected","packageURL":"pkg:npm/vm2","versions":[{"version":"3.11.3","status":"affected","versionType":"semver","lessThan":"3.11.7"},{"version":"3.11.7","status":"unaffected","versionType":"semver"}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"HIGH","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"HIGH","subIntegrityImpact":"HIGH","subAvailabilityImpact":"HIGH","baseScore":9.4,"baseSeverity":"CRITICAL"}},{"format":"CVSS","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH","baseScore":9.9,"baseSeverity":"CRITICAL"}}],"references":[{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-46pr-c5wc-xffx","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-46pr-c5wc-xffx)"},{"name":"VulnCheck Advisory: vm2 3.11.3 through 3.11.6 Native Code Execution via crypto.setEngine","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/vm2-3.11.3-through-3.11.6-native-code-execution-via-crypto-setengine"}],"credits":[{"lang":"en","value":"Forrof","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"references":[{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-46pr-c5wc-xffx","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-17T14:26:12.253959Z","id":"CVE-2026-92939","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-17T14:26:31.623Z"}}]}}
