Prior to 3.11.6, handleException() in lib/setup-sandbox.js sanitizes SuppressedError.error, SuppressedError.suppressed, and AggregateError.errors but does not sanitize Error.cause, allowing sandbox code to obtain a powerful host object such as process from an embedder-exposed host function that throws an error with that object as its cause and then execute arbitrary host commands. This issue is fixed in version 3.11.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-693"],"references":["https://github.com/patriksimek/vm2/commit/7e3faaf550f4ab975bf4cdde183fcec49b056d8e","https://github.com/patriksimek/vm2/releases/tag/3.11.6","https://github.com/patriksimek/vm2/security/advisories/GHSA-m283-3h24-438v"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-47686","score":0.00581,"percentile":0.47485,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-m283-3h24-438v","url":"https://osv.dev/vulnerability/GHSA-m283-3h24-438v","summary":"VM2 has Missing Error.cause Sanitization that Enables Sandbox Escape to RCE","modified":"2026-08-17T17:56:03.690657Z","packages":[{"ecosystem":"npm","name":"vm2","purl":"pkg:npm/vm2","ranges":["<3.11.6"],"fixed":["3.11.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
