CVE-2026-56352Network attack vector

Authenticated file probing and workflow execution via localFile

Published Jul 15, 2026 · Updated Jul 15, 2026

Path traversal in n8n before 2.19.3 allows remote authenticated users to test host file paths through the ExecuteWorkflow REST API. The legacy node accepts localFile from REST-supplied workflow data and reads it without the N8N_RESTRICT_FILE_ACCESS_TO checks used by other file readers. Workflow creation or editing permission is required; arbitrary paths reveal file existence, and valid workflow JSON can be loaded and executed.
