Prior to version 3.11.4, a sandbox escape vulnerability in vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support on runtimes exposing WebAssembly JSPI (WebAssembly.promising / WebAssembly.Suspending). In the tested configuration, a JSPI-backed Promise can reach Promise.prototype.finally() in a way that bypasses the expected Promise-species hardening and exposes a host-originated rejection object to attacker-controlled species logic, breaking the sandbox boundary. This issue has been patched in version 3.11.4.","state":0,"publishedAt":"2026-06-12T14:17:22.653+00:00","modifiedAt":"2026-06-13T03:56:00.069+00:00","affected":[{"ecosystem":"Vendor product","name":"vm2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"patriksimek\",\n                    \"product\": \"vm2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.11.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-6j2x-vhqr-qr7q","https://github.com/patriksimek/vm2/commit/6915fa4d9bcebd47b9a4f39a1adc1aa94ef6ffc6","https://github.com/patriksimek/vm2/releases/tag/v3.11.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-47210","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-47210","identifiers":["CVE-2026-47210"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
