CVE-2026-77068

n8n before 2.34.1 Remote Code Execution via Path Traversal

State: Published
Severity: 8.7 High
Published: Aug 20, 2026
Updated: Aug 25, 2026
Reserved: Aug 20, 2026

Description

n8n before 2.33.4 and 2.34.x before 2.34.1 contain a remote code execution vulnerability in the @n8n/workflow-sdk node-schema loader used for MCP node-schema loading. The loader derives a node's schema module path directly from the attacker-supplied node type string without validating path-traversal sequences. An authenticated user with global:member privileges can reference malicious files via path traversal, causing code execution in the n8n main process.
