{"id":"CVE-2026-92939","summary":"vm2 3.11.3 through 3.11.6 Native Code Execution via crypto.setEngine","details":"vm2 3.11.3 through 3.11.6 exposes the host Node.js crypto module to a NodeVM sandbox when the crypto builtin is allowed. 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.","aliases":["GHSA-46pr-c5wc-xffx"],"modified":"2026-09-19T03:47:29.874700023Z","published":"2026-09-17T13:46:03.558Z","database_specific":{"cwe_ids":["CWE-114"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92939.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92939.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-46pr-c5wc-xffx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92939"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vm2-3.11.3-through-3.11.6-native-code-execution-via-crypto-setengine"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/patriksimek/vm2","events":[{"introduced":"093494c0c3ef2390d2e56909f9d56e290e6f18b0"},{"fixed":"0c5b63a228c0af88d4a0d364ab0b90df278d710e"}],"database_specific":{"extracted_events":[{"introduced":"3.11.3"},{"fixed":"3.11.7"},{"fixed":"3.11.6"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["3.11.6","v3.11.5","v3.11.4","v3.11.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92939.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
