{"id":"CVE-2026-106071","published":"2026-10-23T17:17:20.060","lastModified":"2026-10-23T19:42:24.553","description":"A flaw in Node.js Permission Model filesystem enforcement can grant access to paths that do not match a wildcard `--allow-fs-read` or `--allow-fs-write` rule.\n\nWhen the requested path is shorter than the prefix of a wildcard grant, the radix tree lookup stops comparing early and treats the path as a match. 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**.","cvssScore":3.6,"cvssSeverity":"LOW","cvssVector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-284"],"vendors":[],"products":[],"references":[{"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
