{"id":"CVE-2026-44005","summary":"vm2: Sandbox escape","details":"vm2 is an open source vm/sandbox for Node.js. From 3.9.6 to 3.10.5, vm2's bridge exposes mutable proxies for real host-realm intrinsic prototypes and then forwards sandbox writes into the underlying host objects with otherReflectSet() and otherReflectDefineProperty(), which lets attacker-controlled JavaScript running in a default VM or inherited NodeVM mutate shared host Object.prototype, Array.prototype, and Function.prototype from inside the sandbox This vulnerability is fixed in 3.11.0.","aliases":["GHSA-vwrp-x96c-mhwq"],"modified":"2026-07-08T08:05:14.454009083Z","published":"2026-05-13T17:40:41.578Z","database_specific":{"cwe_ids":["CWE-1321","CWE-94"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44005.json"},"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-44005.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-44005"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44005.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-vwrp-x96c-mhwq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44005"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2477205"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/patriksimek/vm2","events":[{"introduced":"532120d5cdec7da8225fc6242e154ebabc63fe4d"},{"fixed":"fca270df73b64a88e2f9ce71ac17663b6eaf814e"}],"database_specific":{"extracted_events":[{"introduced":"3.9.6"},{"fixed":"3.11.0"}],"cpe":"cpe:2.3:a:vm2_project:vm2:*:*:*:*:*:node.js:*:*","source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44005.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H"}]}
