{"id":"GHSA-9fxx-mv6c-j5xp","summary":"Duplicate Advisory: NodeVM nesting guard accepts array-shaped require and permits host RCE","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-8hr7-r645-pc6w. This link is maintained to preserve external references.\n\n## Original Description\nvm2 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 This issue is fixed in vm2 3.11.7.","modified":"2026-10-01T15:45:06.736368930Z","published":"2026-09-17T15:32:14Z","withdrawn":"2026-10-01T15:32:41Z","database_specific":{"cwe_ids":["CWE-913"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-10-01T15:32:41Z","nvd_published_at":"2026-09-17T14:17:57Z"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/patriksimek/vm2/commit/54b54b74a382577f0bcd0538c5bf99acdcd7f53b"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-nodevm-remote-code-execution-via-array-shaped-require"}],"affected":[{"package":{"name":"vm2","ecosystem":"npm","purl":"pkg:npm/vm2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.11.4"},{"last_affected":"3.11.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-9fxx-mv6c-j5xp/GHSA-9fxx-mv6c-j5xp.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"},{"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
