Sensitive pinned data in n8n

What this means (non-technical)
Pinned data saves a previous execution’s output so you can test downstream nodes without re-running the whole workflow.
If that pinned data includes API responses, database records, or webhook payloads, it may contain passwords, tokens, or personal information.
Pinned data becomes part of the workflow file.
What usually goes wrong
When you export or share the workflow, the pinned data goes with it.
This can accidentally expose:
API tokens.
Customer information.
Email content.
Internal system details.
Because pinned data is meant for testing, it’s easy to forget it’s still there. You might believe you are sharing “just the logic,” but you are also sharing real data.
This often gets discovered later, during audits or after a file has already been shared.
When this becomes urgent
This becomes urgent when:
You share workflows with clients or teammates.
You store workflows in version control.
The pinned data includes production records.
You work under data protection requirements.
The more sensitive the data in your executions, the more careful you need to be with pinned results.
