{"id":"GHSA-8mvv-mcc3-xwhh","summary":"Duplicate Advisory: External module allowlist uses a raw prefix test, so a prefix-sharing sibling package is treated as allowlisted","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-7q3f-wx44-378m. This link is maintained to preserve external references.\n\n## Original Description\nvm2 before 3.11.7 contains a module allowlist bypass vulnerability in isPathAllowedForModule that uses raw string prefix matching instead of boundary-anchored comparison. Attackers can reach non-allowlisted packages sharing a prefix with allowlisted modules by performing relative requires from allowlisted packages when transitive loading is disabled.","modified":"2026-10-01T15:30:05.270273111Z","published":"2026-09-17T15:32:15Z","withdrawn":"2026-10-01T15:26:09Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-10-01T15:26:09Z","nvd_published_at":"2026-09-17T14:17:59Z","cwe_ids":["CWE-22"],"severity":"LOW"},"references":[{"type":"WEB","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-7q3f-wx44-378m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92945"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/vm2-before-3.11.7-module-allowlist-bypass-via-prefix-matching"}],"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-8mvv-mcc3-xwhh/GHSA-8mvv-mcc3-xwhh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/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"}]}
