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."}], "lastModified": "2026-05-14T16:16:23.190", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:vm2_project:vm2:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "6DD48308-6219-4C66-9BE7-246EE56FB834", "versionEndExcluding": "3.11.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
