In versions >= 3.11.4 and <= 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." } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "description": "Improper Control of Dynamically-Managed Code Resources", "cweId": "CWE-913", "type": "CWE" } ] } ], "affected": [ { "vendor": "patriksimek", "product": "vm2", "defaultStatus": "unaffected", "packageURL": "pkg:npm/vm2", "versions": [ { "version": "3.11.4", "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:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H", "attackVector": "NETWORK", "attackComplexity": "HIGH", "attackRequirements": "PRESENT", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "HIGH", "subIntegrityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "baseScore": 9.5, "baseSeverity": "CRITICAL" } }, { "format": "CVSS", "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 9, "baseSeverity": "CRITICAL" } } ], "references": [ { "url": "https://github.com/patriksimek/vm2/security/advisories/GHSA-8hr7-r645-pc6w", "tags": [ "vendor-advisory" ], "name": "GitHub Security Advisory (GHSA-8hr7-r645-pc6w)" }, { "url": "https://github.com/patriksimek/vm2/commit/54b54b74a382577f0bcd0538c5bf99acdcd7f53b", "tags": [ "patch" ], "name": "Patch Commit" }, { "name": "VulnCheck Advisory: vm2 NodeVM Remote Code Execution via Array-Shaped Require", "tags": [ "third-party-advisory" ], "url": "https://www.vulncheck.com/advisories/vm2-nodevm-remote-code-execution-via-array-shaped-require" } ], "credits": [ { "lang": "en", "value": "lexdotdev", "type": "reporter" } ], "x_generator": { "engine": "vulncheck-endgame" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-09-17T18:57:25.525605Z", "id": "CVE-2026-92935", "options": [ { "Exploitation": "none" }, { "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": "2026-09-17T19:21:04.162Z" } } ] } }
