{"id":"CVE-2026-47140","aliases":["GHSA-rp36-8xq3-r6c4"],"url":"https://o3.security/vulnerability/CVE-2026-47140","summary":"vm2: NodeVM builtin denylist bypass via process and inspector/promises allows host code execution","details":"vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM blocks several dangerous Node.js builtins such as module, worker_threads, cluster, vm, repl, and inspector. However, the denylist misses process and inspector/promises. Both can be used from sandboxed code to reach host-side execution primitives. This allows sandboxed code to bypass the intended builtin restrictions and execute code in the host process. This issue has been patched in version 3.11.4.","published":"2026-06-12T14:16:10.727Z","modified":"2026-08-12T03:51:17.416355172Z","cvss":{"score":10,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.00817,"percentile":0.53738,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"vm2","fixedVersion":"3.11.4"}],"fix":{"url":"https://github.com/patriksimek/vm2/commit/a1ed47a98d1cc36cb48c0d566d55889688e0b59b","label":"patriksimek/vm2@a1ed47a"},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/releases/tag/v3.11.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47140.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-rp36-8xq3-r6c4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47140"},{"type":"FIX","url":"https://github.com/patriksimek/vm2/commit/a1ed47a98d1cc36cb48c0d566d55889688e0b59b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.416355172Z"}}
