GHSA-33Q9-F52J-GC75 n8n: Unauthenticated Endpoint Allows Cancellation of Any User's Active Test Webhook

Impact The DELETE /$restEndpoint/test-webhook/:id route is registered before the authentication middleware is applied, allowing any unauthenticated network caller who knows a workflow ID to cancel that workflow's active test webhook registration. The impact is limited to disrupting in-progress te...

n8n: GraphQL Node Bypasses "Allowed HTTP Request Domains" Restriction
