CVE-2026-118649n8n before 2.43.5 and 2.44.1 Authorization Bypass via Crafted Workflow ID in Data Tables

Beschreibung

n8n before 2.43.5 and 2.44.x before 2.44.1 accepts a client-supplied workflow ID and caches each workflow's owner project in memory by that ID, so a crafted ID such as __proto__ makes the Data Table project check match every project. An authenticated member who can create and run workflows can list, read, modify, and delete Data Table rows in all projects of the instance.
