CVE-2026-72765Network attack vectorHinoki check available

Authenticated command execution via expression sandbox escape

Published Aug 11, 2026 · Updated Aug 11, 2026

Code injection in n8n before 2.31.5 and before 2.32.1 allows remote authenticated users to execute host commands through expressions. The expression evaluator accepts crafted arrow-function bodies that escape its sandbox and reach system command execution. Exploitation requires permission to create or modify workflows, and commands run with the privileges of the n8n process.
