n8n before 1.123.83 contains an authorization bypass vulnerability that allows shared-workflow editors to use credentials they cannot access by embedding them in nested or tool inline sub-workflows. Attackers can save workflows with Workflow Tool or Workflow Retriever inline definitions referencing restricted credentials, which execute using the workflow owner's credential values.
