CVE-2026-58043 is an improper authorization flaw in Node.js Permission Model filesystem enforcement. When Node.js runs with the --permission option, radix-tree prefix-boundary handling can over-grant access: authorization for one filesystem path may incorrectly match paths outside the intended allowlist. The flaw affects Node.js main, 22.x, 24.x, and 26.x release lines.
