Attackers can exploit this by creating an async function that returns a Promise with an attacker-controlled constructor Symbol.species, allowing them to reach the host Function constructor and process object for arbitrary code execution.","published":"2026-09-17T13:46:06.201Z","modified":"2026-09-18T03:48:43.119599584Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/patriksimek/vm2/commit/4635ddd85839461c8ad791990023a477efefe7bd","label":"patriksimek/vm2@4635ddd"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92944.json"},{"type":"FIX","url":"https://github.com/patriksimek/vm2/commit/4635ddd85839461c8ad791990023a477efefe7bd"},{"type":"FIX","url":"https://github.com/patriksimek/vm2/commit/7b26e81087ec88c287d9a4812f969d412f32774e"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-27g9-p43v-cw3v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92944"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vm2-3.10.2-through-3.11.6-sandbox-escape-via-promise-protector"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T03:48:43.119599584Z"}}
