{"id":"GHSA-wqg3-r97q-73xm","summary":"Duplicate Advisory: NodeVM builtin allowlist bypass via node:test.run() execArgv allows sandbox escape","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-qhwx-74w5-xhxq. This link is maintained to preserve external references.\n\n## Original Description\nvm2 versions \u003e= 3.9.6 and \u003c= 3.11.6 are affected by a NodeVM builtin allowlist bypass that permits a sandbox escape on Node.js 24 and newer when the embedder explicitly allows the node:test builtin (e.g. require: { builtin: ['node:test'] }). On Node.js 24+, module.builtinModules exposes the scheme-only key node:test, which is not covered by vm2's family-based DANGEROUS_BUILTINS protection, so it is stored in the generic host-passthrough loader. Because requireImpl() in lib/setup-node-sandbox.js strips a single 'node:' prefix before the builtin lookup, sandbox code calling require('node:node:test') resolves to the stored node:test key and receives a readonly proxy to the host module. Calls to node:test.run() are forwarded to the host implementation, which spawns a separate Node process for process-isolated test execution and passes through attacker-controlled execArgv values; supplying --eval=\u003cJavaScript\u003e therefore executes arbitrary JavaScript in an unrestricted host Node process outside the NodeVM sandbox. Fixed in vm2 3.11.7.","modified":"2026-10-01T16:00:04.777319536Z","published":"2026-09-17T15:32:15Z","withdrawn":"2026-10-01T15:41:04Z","database_specific":{"github_reviewed_at":"2026-10-01T15:41:04Z","nvd_published_at":"2026-09-17T14:18:00Z","cwe_ids":["CWE-693"],"severity":"CRITICAL","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-qhwx-74w5-xhxq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92948"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-3.9.6-through-3.11.5-sandbox-escape-via-node-test"}],"affected":[{"package":{"name":"vm2","ecosystem":"npm","purl":"pkg:npm/vm2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.9.6"},{"last_affected":"3.11.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-wqg3-r97q-73xm/GHSA-wqg3-r97q-73xm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"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/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"}]}
