{"id":"GHSA-hwr5-cm8v-c76q","summary":"Duplicate Advisory: vm2 sandbox escape on Node.js 26 through a stale PromiseThenLookupChain protector","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-27g9-p43v-cw3v. This link is maintained to preserve external references.\n\n## Original Description\nvm2 versions 3.10.2 through 3.11.6 contain a sandbox escape vulnerability on Node.js 26 where Promise.prototype.finally() bypasses vm2's wrapper protections due to a stale PromiseThenLookupChain protector in V8 14.6. 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object for arbitrary code execution.","modified":"2026-10-01T15:45:06.204104759Z","published":"2026-09-17T15:32:14Z","withdrawn":"2026-10-01T15:27:57Z","database_specific":{"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-10-01T15:27:57Z","nvd_published_at":"2026-09-17T14:17:59Z","cwe_ids":["CWE-693"]},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/patriksimek/vm2/commit/4635ddd85839461c8ad791990023a477efefe7bd"},{"type":"WEB","url":"https://github.com/patriksimek/vm2/commit/7b26e81087ec88c287d9a4812f969d412f32774e"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-3.10.2-through-3.11.6-sandbox-escape-via-promise-protector"}],"affected":[{"package":{"name":"vm2","ecosystem":"npm","purl":"pkg:npm/vm2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.10.2"},{"last_affected":"3.11.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-hwr5-cm8v-c76q/GHSA-hwr5-cm8v-c76q.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
