CWE-918

Description

n8n versions before 2.32.1 contain a server-side request forgery protection bypass vulnerability in the MCP Client node that allows authenticated users to bypass SSRF protections. Attackers can craft workflows that send requests to internal or blocked hosts without routing through SSRF protection, exposing internal services and reading responses back through the workflow.

Affected configurations

• n8n n8n (>= 2.31.0 < 2.31.5) • n8n n8n 2.32.0
