Detailsinfo

A vulnerability classified as problematic has been found in n8n-io n8n up to 2.32.0. This affects some unknown processing of the component MCP Client node. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-72768 since 08/10/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. The technical details are unknown and an exploit is not publicly available.
