{"id":"CVE-2026-44001","aliases":["GHSA-hw58-p9xv-2mjh"],"url":"https://o3.security/vulnerability/CVE-2026-44001","summary":"vm2: Sandbox Escape via Promise Constructor Unhandled Rejection (Process Crash DoS)","details":"vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for CVE-2026-22709 (v3.10.2) only sanitized the onRejected callback in .then() and .catch() overrides and did not address the executor-to-unhandledRejection path. This vulnerability is fixed in 3.11.0.","published":"2026-05-13T17:29:00.289Z","modified":"2026-08-08T03:30:18.010781777Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"vm2","fixedVersion":"3.11.0"}],"fix":null,"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-44001.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:50850"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-44001"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44001.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-hw58-p9xv-2mjh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44001"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2477208"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:30:18.010781777Z"}}
