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." } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "description": "Uncaught Exception", "cweId": "CWE-248", "type": "CWE" } ] } ], "affected": [ { "vendor": "patriksimek", "product": "vm2", "defaultStatus": "unaffected", "packageURL": "pkg:npm/vm2", "versions": [ { "version": "3.10.0", "status": "affected", "versionType": "semver", "lessThan": "3.11.8" }, { "version": "3.11.8", "status": "unaffected", "versionType": "semver" } ] } ], "metrics": [ { "format": "CVSS", "cvssV4_0": { "version": "4.0", "vectorString": "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", "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "NONE", "vulnIntegrityImpact": "NONE", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "subAvailabilityImpact": "HIGH", "baseScore": 9.2, "baseSeverity": "CRITICAL" } }, { "format": "CVSS", "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "baseScore": 8.6, "baseSeverity": "HIGH" } } ], "references": [ { "url": "https://github.com/patriksimek/vm2/security/advisories/GHSA-gjq8-xm47-88rc", "tags": [ "vendor-advisory" ], "name": "GitHub Security Advisory (GHSA-gjq8-xm47-88rc)" }, { "name": "VulnCheck Advisory: vm2 3.10.0 through 3.11.5 Denial of Service via Host Promise", "tags": [ "third-party-advisory" ], "url": "https://www.vulncheck.com/advisories/vm2-3.10.0-through-3.11.5-denial-of-service-via-host-promise" } ], "credits": [ { "lang": "en", "value": "rexpository", "type": "reporter" } ], "x_generator": { "engine": "vulncheck-endgame" } }, "adp": [ { "references": [ { "url": "https://github.com/patriksimek/vm2/security/advisories/GHSA-gjq8-xm47-88rc", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-09-21T17:15:31.102120Z", "id": "CVE-2026-92954", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-09-21T17:15:56.296Z" } } ] } }
