{"id":"CVE-2026-92951","summary":"vm2 before 3.11.7 Module Allowlist Bypass via Custom Resolver","details":"vm2 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.","aliases":["GHSA-c48m-32m9-vx93"],"modified":"2026-09-19T03:47:29.840527720Z","published":"2026-09-17T13:46:10.792Z","database_specific":{"cwe_ids":["CWE-706"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92951.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92951.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/vm2-before-3.11.7-module-allowlist-bypass-via-custom-resolver"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/patriksimek/vm2","events":[{"introduced":"0"},{"fixed":"0c5b63a228c0af88d4a0d364ab0b90df278d710e"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"3.11.7"},{"introduced":"vm2"}]}}],"versions":["3.11.6","v3.11.5","v3.11.4","v3.11.3","v3.11.2","v3.11.1","v3.11.0","v3.10.5","v3.10.4","v3.10.3","v3.10.2","v3.10.1","v3.10.0","3.9.19","3.9.18","3.9.17","3.9.16","3.9.15","3.9.14","3.9.13","3.9.12","3.9.11","3.9.10","3.9.9","3.9.8","3.9.7","3.9.6","3.9.5","3.9.4","3.9.3","v3.9.2","v3.9.1","v3.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92951.json"}}],"schema_version":"1.9.0","severity":[{"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"}]}
