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.","state":0,"publishedAt":"2026-09-17T13:46:03.558+00:00","modifiedAt":"2026-09-17T14:26:31.623+00:00","affected":[{"ecosystem":"Vendor product","name":"vm2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"patriksimek\",\n                    \"product\": \"vm2\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/vm2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"3.11.3\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.11.7\"\n                        },\n                        {\n                            \"version\": \"3.11.7\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":9.4,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-46pr-c5wc-xffx","https://www.vulncheck.com/advisories/vm2-3.11.3-through-3.11.6-native-code-execution-via-crypto-setengine"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92939","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92939","identifiers":["CVE-2026-92939"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
