Prior to 3.11.0, vm2's code transformer has a performance optimization that skips AST analysis when the code does not contain catch, import, or async keywords. This fast-path bypass allows sandboxed code to directly access the internal VM2_INTERNAL_STATE_DO_NOT_USE_OR_PROGRAM_WILL_FAIL variable, which exposes internal security functions (handleException, wrapWith, import). This vulnerability is fixed in 3.11.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":5.8},"cwes":["CWE-693"],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-wp5r-2gw5-m7q7","https://github.com/patriksimek/vm2/security/advisories/GHSA-wp5r-2gw5-m7q7"],"products":["vm2_project:vm2"],"source":"nvd","synced_at":"2026-10-26T17:39:09.812804557+00:00"},"epss":{"cve":"CVE-2026-44003","score":0.00248,"percentile":0.15982,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-wp5r-2gw5-m7q7","url":"https://osv.dev/vulnerability/GHSA-wp5r-2gw5-m7q7","summary":"vm2's Transformer Fast-Path Bypass Exposes Internal State Variable","modified":"2026-05-14T20:52:36.062511Z","packages":[{"ecosystem":"npm","name":"vm2","purl":"pkg:npm/vm2","ranges":["<3.11.0"],"fixed":["3.11.0"]}]}],"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).
