Prior to version 3.11.4, NodeVM supports excluding public network builtins from the wildcard builtin option. With this configuration direct access to http, https, http2, net, dgram, tls, dns, and dns/promises is blocked. However, Node.js also exposes underscored internal HTTP builtins such as _http_client and _http_server. These are not blocked when the public modules are excluded. Sandboxed code can use these internal builtins to make outbound HTTP requests and open listening HTTP sockets even though the public network modules are denied. This issue has been patched in version 3.11.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6},"cwes":["CWE-693"],"references":["https://github.com/patriksimek/vm2/commit/436053e30eecbabd487e2fd2959c137ac34e2bb1","https://github.com/patriksimek/vm2/releases/tag/v3.11.4","https://github.com/patriksimek/vm2/security/advisories/GHSA-r9pm-gxmw-wv6p","https://github.com/patriksimek/vm2/security/advisories/GHSA-r9pm-gxmw-wv6p"],"products":[],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-47139","score":0.00282,"percentile":0.2056,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-r9pm-gxmw-wv6p","url":"https://osv.dev/vulnerability/GHSA-r9pm-gxmw-wv6p","summary":"NodeVM network builtin exclusions bypass via internal _http_client and _http_server","modified":"2026-06-12T19:45:09.837553446Z","packages":[{"ecosystem":"npm","name":"vm2","purl":"pkg:npm/vm2","ranges":["<3.11.4"],"fixed":["3.11.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
