{"id":"GHSA-5v7w-95g5-pj6q","summary":"Duplicate Advisory: Default VM can mutate host TypedArray and ArrayBuffer intrinsics after the host-prototype pollution fix","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-3vgf-8m4q-q4qr. This link is maintained to preserve external references.\n\n## Original Description\nvm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arrays to observe attacker-controlled properties after VM.run() returns.","modified":"2026-10-05T23:00:04.247984162Z","published":"2026-09-17T15:32:16Z","withdrawn":"2026-10-05T22:45:04Z","database_specific":{"github_reviewed_at":"2026-10-05T22:45:04Z","nvd_published_at":"2026-09-17T14:18:01Z","cwe_ids":["CWE-913"],"severity":"CRITICAL","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-3vgf-8m4q-q4qr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92953"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-3.11.0-through-3.11.7-prototype-pollution-via-typedarray"}],"affected":[{"package":{"name":"vm2","ecosystem":"npm","purl":"pkg:npm/vm2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.11.0"},{"last_affected":"3.11.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-5v7w-95g5-pj6q/GHSA-5v7w-95g5-pj6q.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/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"}]}
