CVE-2026-77068
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.
Overview
CVE-2026-77068 is a known-severity vulnerability. It was published on August 20, 2026.
Technical 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.

How can CyberStrike help with CVE-2026-77068?
CyberStrike is an open-source, AI-augmented pentesting engine.
