CVE-2026-106071

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. When 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...

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...

CVE-2026-106071

Node.js Permission Model radix-tree lookup over-grants filesystem access: for a wildcard grant such as /tmp/test, paths that are a prefix of the grant e.g. /tmp/tes are treated as granted. Fixed in 26.12.1...

CVE-2026-106073

Node.js Permission Model bypass: fs.realpathSync walks the path with internal lstat calls that perform no permission check, so it can resolve and probe paths outside the allowed filesystem scope. Fixed in 22.23.4, 24.22.1 and 26.12.1...
