{"id":"CVE-2026-47141","summary":"vm2: NodeVM observability builtins leak host process and HTTP request data","details":"vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The diagnostics_channel, async_hooks, and perf_hooks builtins are not blocked by the dangerous builtin denylist. These modules are process-wide, not sandbox-local. Sandboxed code can use them to observe host application data across the vm2 boundary. This issue has been patched in version 3.11.4.","aliases":["GHSA-9g8x-92q2-p28f"],"modified":"2026-07-08T08:13:37.141007553Z","published":"2026-06-12T14:17:35.970Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-668"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47141.json"},"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-2026-47141.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-9g8x-92q2-p28f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47141"},{"type":"FIX","url":"https://github.com/patriksimek/vm2/commit/e1c48fce05189f48e71efbd32af0754efa4066bb"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/patriksimek/vm2","events":[{"introduced":"0"},{"fixed":"e1c48fce05189f48e71efbd32af0754efa4066bb"},{"fixed":"27354d56563b0acb54eb9dd92edbc167612b9d4b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.11.4"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v3.11.3","v3.11.2","v3.11.1","v3.11.0","v3.10.5","v3.10.4","v3.10.3","v3.10.2","v3.10.1","v3.10.0","3.9.19","3.9.18","3.9.17","3.9.16","3.9.15","3.9.14","3.9.13","3.9.12","3.9.11","3.9.10","3.9.9","3.9.8","3.9.7","3.9.6","3.9.5","3.9.4","3.9.3","v3.9.2","v3.9.1","v3.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47141.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
