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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"patriksimek","product":"vm2","versions":[{"version":"< 3.11.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-12T00:00:00+00:00","id":"CVE-2026-47210","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-913"}]}],"references":[{"url":"https://github.com/patriksimek/vm2/commit/6915fa4d9bcebd47b9a4f39a1adc1aa94ef6ffc6","source":"security-advisories@github.com"},{"url":"https://github.com/patriksimek/vm2/releases/tag/v3.11.4","source":"security-advisories@github.com"},{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-6j2x-vhqr-qr7q","source":"security-advisories@github.com"},{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-6j2x-vhqr-qr7q","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
