CVE-2026-59207 · n8n: "Allowed HTTP Request Domains" Restriction Bypass via AI Agents MCP Connector

This page contains facts from public vulnerability sources. Check the original advisory before updating.

n8n is an open source workflow automation platform. Prior to 2.27.4 and 2.28.1, the AI Agents feature did not enforce the Allowed HTTP Request Domains restriction configured on credentials when an MCP tool was pointed at an arbitrary URL, allowing a member-level user with use-only access to a shared credential to send its secret to an external server they control. This issue is fixed in versions 2.27.4 and 2.28.1.
