CVE-2026-1470Public exploitNetwork attack vector

Authenticated code execution via with-statement sandbox escape

Published Jan 27, 2026 · Updated Jan 27, 2026

Expression injection in n8n before 1.123.17, 2.0.0 through 2.4.4, and 2.5.0 allows remote authenticated users to execute code. The expression sandbox accepts a with statement that manipulates constructor resolution, exposing Function construction and Node.js child_process execution. Workflow creation or modification access is required; code runs as the n8n process and can read sensitive data, alter workflows, and invoke system operations.
