CVE-2026-77068Network attack vector

Authenticated code execution via node-schema path traversal

Published Aug 20, 2026 · Updated Aug 25, 2026

Path traversal in n8n 2.0.0 through 2.33.3 and 2.34.0 allows remote authenticated users to execute code in the main process. The @n8n/workflow-sdk node-schema loader constructs a schema module path directly from an attacker-controlled node type without rejecting traversal sequences. A global:member account and Instance-level MCP schema loading are required, and successful exploitation runs referenced malicious files with the n8n process privileges.
