CyberRota Analysis
AI-GeneratedVersions of n8n prior to 2.32.1 are vulnerable to a server-side request forgery (SSRF) protection bypass in the MCP Client node, allowing authenticated users to exploit this flaw. This vulnerability enables attackers to craft workflows that can send requests to internal or restricted hosts, potentially exposing sensitive internal services and retrieving their responses. Organizations using affected n8n versions should prioritize patching to mitigate the risk of unauthorized access to internal resources.

Original NVD 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.
