CVE-2026-77068: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in n8n-io n8n
Description
n8n versions before 2.33.4 and 2.34.x before 2.34.1 contain a remote code execution vulnerability due to improper validation of pathname inputs in the node-schema loader. An authenticated user with global:member privileges can exploit path traversal sequences to execute arbitrary code in the main n8n process.

Technical Analysis
CVE-2026-77068 is a remote code execution vulnerability in n8n's @n8n/workflow-sdk node-schema loader. The loader constructs a node's schema module path directly from an attacker-controlled node type string without validating for path traversal sequences. This allows an authenticated user with global:member privileges to reference malicious files via path traversal, leading to code execution within the n8n main process. The vulnerability affects versions >=2.0.0 <2.33.4 and >=2.34.0 <2.34.1.
Potential Impact
Successful exploitation allows an authenticated user with global:member privileges to execute arbitrary code on the n8n server process. This can lead to full compromise of the affected system running n8n.
Mitigation Recommendations
A fix is available in n8n versions 2.33.4 and 2.34.1 and later. Users should upgrade to these versions or later to remediate this vulnerability.
