CVE-2026-106073
A flaw in Node.js Permission Model filesystem enforcement leaves `fs.realpathSync()` without the required read permission checks. This is an incomplete fix of CVE-2026-21715, which only covered `fs.realpathSync.native()`. As 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. This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.
CVE-2026-106073 is fixed in 32 products on 2 platforms, first by Node.js (LTS) 24.22.1, released October 20, 2026. It is not reported as exploited. Patch Radar priority: High.
