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**.","epss":{"date":"2026-11-02","percentile":0.09795,"score":0.00199},"exploits":[],"kev":null,"metrics":[{"score":3.6,"severity":"low","source":"CNA: hackerone","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","version":"3.0"},{"score":3.6,"severity":"low","source":"NVD: support@hackerone.com","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.0"}],"modifiedAt":1793636245067,"publishedAt":1792772105791,"references":[{"source":"CNA: hackerone","tags":[],"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"},{"source":"support@hackerone.com","tags":[],"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"}],"remediation":[],"revision":"1247d41f9c9c18f635243c3c4a2f87fe5ebd249965497742b8a959b9f5dbdf51","sources":[{"modifiedAt":1793634027184,"name":"CNA: hackerone","retrievedAt":1793635707489,"url":"https://www.cve.org/CVERecord?id=CVE-2026-106071"},{"modifiedAt":1793636245067,"name":"NVD","retrievedAt":1793643424879,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106071"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793635727182,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-106071"}],"ssvc":{"assessedAt":1793634016898,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"CVE-2026-106071","updatedAt":1793643424879}
