{"id":"GHSA-6fvh-fgmg-3x7v","summary":"Duplicate Advisory: vm2 Custom Module Resolver Can Bypass the External Package Allowlist by Loading a Colliding Host Package","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-c48m-32m9-vx93. This link is maintained to preserve external references.\n\n## Original Description\nvm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowlisted package substring, causing vm2 to load and execute unauthorized host packages in the host context.","modified":"2026-10-01T15:45:05.633384784Z","published":"2026-09-17T15:32:16Z","withdrawn":"2026-10-01T15:37:00Z","database_specific":{"github_reviewed_at":"2026-10-01T15:37:00Z","nvd_published_at":"2026-09-17T14:18:00Z","cwe_ids":["CWE-706"],"severity":"CRITICAL","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-c48m-32m9-vx93"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92951"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-before-3.11.7-module-allowlist-bypass-via-custom-resolver"}],"affected":[{"package":{"name":"vm2","ecosystem":"npm","purl":"pkg:npm/vm2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"3.11.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-6fvh-fgmg-3x7v/GHSA-6fvh-fgmg-3x7v.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"}]}
