GHSA-2CF7-HPWF-47H9 n8n-MCP: Incorrect authorization can expose default-scope workflow version backups in multi-tenant HTTP mode
Summary In multi-tenant HTTP mode ENABLEMULTITENANT=true, an authenticated tenant could, under certain conditions, reach n8n-mcp's local default-scope workflowversions backups instead of being confined to its own tenant scope. This affects n8n-mcp's own local workflow-version storage, not a norma...
