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**.","published":"2026-10-23T17:17:20.000Z","lastModified":"2026-10-23T19:42:25.000Z","status":"Awaiting Analysis","sourceIdentifier":"support@hackerone.com","cvss":{"version":"3.0","score":3.6,"severity":"LOW","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},"cwe":["CWE-284"],"affected":[],"epss":{"score":0.00193,"percentile":0.08842,"date":"2026-10-26","history":[{"date":"2026-10-24","score":0.0014,"percentile":0.03015}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.19%).
