Prior to 3.11.6, handleException() in lib/setup-sandbox.js sanitizes SuppressedError.error, SuppressedError.suppressed, and AggregateError.errors but does not sanitize Error.cause, allowing sandbox code to obtain a powerful host object such as process from an embedder-exposed host function that throws an error with that object as its cause and then execute arbitrary host commands. This issue is fixed in version 3.11.6.","state":0,"publishedAt":"2026-08-17T20:54:39.406+00:00","modifiedAt":"2026-08-19T03:56:00.965+00:00","affected":[{"ecosystem":"Vendor product","name":"vm2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"patriksimek\",\n                    \"product\": \"vm2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.11.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-m283-3h24-438v","https://github.com/patriksimek/vm2/commit/7e3faaf550f4ab975bf4cdde183fcec49b056d8e","https://github.com/patriksimek/vm2/releases/tag/3.11.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-47686","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-47686","identifiers":["CVE-2026-47686"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
