n8n HTTP Request node credential domain allowlist bypass
In n8n (open-source workflow automation), versions prior to 1.121.0 contain a flaw in the HTTP Request node’s credential domain validation logic. When credentials are configured with wildcard patterns in the “Allowed domains” setting (e.g., *.example.com), an authenticated attacker can bypass the intended domain restriction and cause the HTTP Request node to send requests to unintended domains while still attaching the stored credentials. This can result in credential exposure/exfiltration to attacker-controlled endpoints. The issue is fixed in n8n 1.121.0 and later.
