{"id":"GHSA-6jgm-4w45-vh8j","summary":"Duplicate Advisory: vm2 crypto builtin loads attacker native code through setEngine","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-46pr-c5wc-xffx. This link is maintained to preserve external references.\n\n## Original Description\nvm2 3.11.3 through 3.11.6 exposes the host Node.js crypto module to a NodeVM sandbox when the crypto builtin is allowed. The module is presented via a recursive read-only proxy, but its callable exports still execute with host-process authority. Sandboxed JavaScript can therefore call crypto.setEngine() with a filesystem path to an attacker-supplied native library (for example, one bundled in an untrusted plugin package already written to disk); OpenSSL asks the operating-system dynamic loader to load the file, and the library's constructor executes native code in the host process before engine-symbol validation rejects it. Exploitation requires only the crypto builtin and does not require fs, process, module, child_process, worker_threads, vm, or inspector access, resulting in a sandbox escape and arbitrary native code execution. Fixed in 3.11.7.","modified":"2026-10-01T15:45:06.202722723Z","published":"2026-09-17T15:32:14Z","withdrawn":"2026-10-01T15:28:21Z","database_specific":{"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-10-01T15:28:21Z","nvd_published_at":"2026-09-17T14:17:58Z","cwe_ids":["CWE-114"]},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-46pr-c5wc-xffx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92939"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-3.11.3-through-3.11.6-native-code-execution-via-crypto-setengine"}],"affected":[{"package":{"name":"vm2","ecosystem":"npm","purl":"pkg:npm/vm2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.11.3"},{"last_affected":"3.11.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-6jgm-4w45-vh8j/GHSA-6jgm-4w45-vh8j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
