This is an incomplete fix of CVE-2026-21715, which only covered `fs.realpathSync.native()`.\n\nAs a result, code running under `--permission` with restricted `--allow-fs-read` can still use `fs.realpathSync()` to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/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}
