For example, `--allow-fs-read=/etc/passwd.*` also allows reading `/etc/passwd`. This requires the wildcard grant to sit directly under the root of the permission tree, for example when it is the only grant for that scope. This is a different root cause from CVE-2026-58043.\n\nThis vulnerability affects Node.js **26.x**.","state":0,"publishedAt":"2026-10-23T16:15:05.791+00:00","modifiedAt":"2026-10-23T16:15:05.791+00:00","affected":[{"ecosystem":"Vendor product","name":"node","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"nodejs\",\n                    \"product\": \"node\",\n                    \"versions\": [\n                        {\n                            \"version\": \"26.12.0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"26.12.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N/CR:M/IR:M/AR:M","score":3.6,"severity":"LOW"}],"references":["https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106071","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106071","identifiers":["CVE-2026-106071"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
