{"id":"CVE-2026-22709","aliases":["GHSA-99p7-6v5w-7xg8"],"url":"https://o3.security/vulnerability/CVE-2026-22709","summary":"vm2 has a Sandbox Escape","details":"vm2 is an open source vm/sandbox for Node.js. In vm2 prior to version 3.10.2, `Promise.prototype.then` `Promise.prototype.catch` callback sanitization can be bypassed. This allows attackers to escape the sandbox and run arbitrary code. In lib/setup-sandbox.js, the callback function of `localPromise.prototype.then` is sanitized, but `globalPromise.prototype.then` is not sanitized. The return value of async functions is `globalPromise` object. Version 3.10.2 fixes the issue.","published":"2026-01-26T21:32:00.215Z","modified":"2026-08-12T03:51:17.399536573Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"vm2","fixedVersion":"3.10.2"}],"fix":{"url":"https://github.com/patriksimek/vm2/commit/4b009c2d4b1131c01810c1205e641d614c322a29","label":"patriksimek/vm2@4b009c2"},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/releases/tag/v3.10.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22709.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-99p7-6v5w-7xg8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22709"},{"type":"FIX","url":"https://github.com/patriksimek/vm2/commit/4b009c2d4b1131c01810c1205e641d614c322a29"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.399536573Z"}}
