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.","state":0,"publishedAt":"2026-05-13T17:30:38.883+00:00","modifiedAt":"2026-05-13T18:41:25.611+00:00","affected":[{"ecosystem":"Vendor product","name":"vm2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"patriksimek\",\n                    \"product\": \"vm2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.11.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-wp5r-2gw5-m7q7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44003","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44003","identifiers":["CVE-2026-44003"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
