GHSA-679F-58PQ-4V2C n8n: Prototype Pollution via Workflow Structure Summary Can Lead to Denial of Service

Impact The Instance AI workflow summary built its result with get-or-create-then-nested-write idioms keyed by node names and connection keys taken from the stored workflow. Those are arbitrary strings: the restricted-name guard n8n shows in the editor is client-side and is bypassed by posting the...
