{"id":"CVE-2026-92935","summary":"vm2 NodeVM Remote Code Execution via Array-Shaped Require","details":"vm2 is a sandbox for running untrusted Node.js code. In versions \u003e= 3.11.4 and \u003c= 3.11.6, the NodeVM constructor computes `hasRealRequireConfig` with `typeof requireOpts === 'object' && requireOpts !== null`, so an array-shaped `require` value (for example `require: []`) satisfies the guard that is meant to reject nesting without an explicit require configuration. `makeResolverFromLegacyOptions()` then destructures the array into undefined option fields and returns a resolver containing only `NESTING_OVERRIDE.vm2`. As a result, an attacker who can supply JavaScript executed by a NodeVM configured with truthy `nesting` and an array-shaped `require` (e.g. `new NodeVM({nesting: true, require: []})`) can require the host `vm2` module, create an inner NodeVM with an attacker-chosen builtin allowlist (such as `child_process`), and execute arbitrary commands with the privileges of the host Node.js process, escaping the sandbox. Outer builtin restrictions do not constrain the attacker-created inner NodeVM. This issue is fixed in vm2 3.11.7.","aliases":["GHSA-8hr7-r645-pc6w"],"modified":"2026-09-19T03:47:29.804220675Z","published":"2026-09-17T13:46:00.854Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-913"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92935.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92935.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-8hr7-r645-pc6w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92935"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vm2-nodevm-remote-code-execution-via-array-shaped-require"},{"type":"FIX","url":"https://github.com/patriksimek/vm2/commit/54b54b74a382577f0bcd0538c5bf99acdcd7f53b"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/patriksimek/vm2","events":[{"introduced":"27354d56563b0acb54eb9dd92edbc167612b9d4b"},{"fixed":"54b54b74a382577f0bcd0538c5bf99acdcd7f53b"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"3.11.4"},{"fixed":"3.11.7"}]}}],"versions":["3.11.6","v3.11.5","v3.11.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92935.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"}]}
