CyberRota Analysis
AI-GeneratedThe vulnerability allows authenticated users with read-only access to trigger execution of workflows via the POST /workflows/{workflowId}/test-runs/new endpoint, bypassing proper authorization checks. This can lead to unintended outbound API calls and data mutations in connected systems, posing significant risks to data integrity and security. Organizations using n8n versions prior to 1.123.55, 2.25.7, and 2.26.2, particularly those utilizing the Evaluations feature with restrictive RBAC roles, should prioritize patching this issue.

Original NVD Description
n8n before 1.123.55, 2.25.7, and 2.26.2 contains an authorization bypass in the POST /workflows/{workflowId}/test-runs/new endpoint, which authorizes access using the workflow:read scope instead of workflow:execute. An authenticated user with read-only access to a workflow can trigger a real evaluation test run, causing the workflow to execute via the internal workflow runner and resulting in unintended outbound API calls, data mutations, or other side effects in connected downstream systems. The issue primarily affects instances using the Evaluations feature where RBAC project roles grant workflow:read without workflow:execute.
