In versions >= 3.10.0 and <= 3.11.7, Promises returned from the host realm into the sandbox are not marked as handled at the bridge boundary; only Promises created inside the sandbox are wrapped with a rejection-swallowing handler (lib/setup-sandbox.js), and the bridge only installs host-side rejection sanitizers when sandbox code calls .then/.catch/.finally. As a result, code running in the sandbox can invoke a host function that returns a rejected Promise (for example events.once() exposed via the NodeVM events builtin, or any embedder-provided Promise-returning API) and simply ignore the return value, leaving the host Promise unhandled so that Node.js's default unhandled-rejection behavior terminates the host process. This is an incomplete fix of GHSA-hw58-p9xv-2mjh. The issue is fixed in version 3.11.8.","state":0,"publishedAt":"2026-09-17T13:46:12.82+00:00","modifiedAt":"2026-09-26T13:30:00.813+00:00","affected":[{"ecosystem":"Vendor product","name":"vm2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"patriksimek\",\n                    \"product\": \"vm2\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/vm2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"3.10.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.11.8\"\n                        },\n                        {\n                            \"version\": \"3.11.8\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","score":9.2,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","score":8.6,"severity":"HIGH"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-gjq8-xm47-88rc","https://www.vulncheck.com/advisories/vm2-3.10.0-through-3.11.5-denial-of-service-via-host-promise"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92954","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92954","identifiers":["CVE-2026-92954"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
