Prior to 3.11.0, NodeVM's builtin allowlist can be bypassed when the module builtin is allowed (including via the '*' wildcard). The module builtin exposes Node's Module._load(), which loads any module by name directly in the host context, completely bypassing vm2's builtin restriction. This allows sandboxed code to load excluded builtins like child_process and achieve remote code execution. This vulnerability is fixed in 3.11.0.","state":0,"publishedAt":"2026-05-13T18:16:16.45+00:00","modifiedAt":"2026-10-26T17:10:03.27+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"},{"system":"CVSS 3.1 · 0b0ca135-0b70-47e7-9f44-1890c2a1c46c · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-947f-4v7f-x2v8","https://access.redhat.com/errata/RHSA-2026:50850","https://access.redhat.com/security/cve/CVE-2026-43999","https://bugzilla.redhat.com/show_bug.cgi?id=2477196","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-43999.json"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-43999","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-863","CWE-829"],"productCriteria":["cpe:2.3:a:vm2_project:vm2:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-05-13T18:16:16.450","lastModified":"2026-10-26T17:10:03.270"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
