- Check your version: run
npm ls n8n. Versions < 1.123.55 of n8n are affected. [1]
What to do now
- Upgrade to the fixed version: run
npm install n8n@1.123.55(first patched version 1.123.55). [1] - Upgrade to one of these versions or later to remediate the vulnerability. [1]
- If upgrading is not immediately possible, administrators should consider restricting workflow access to fully trusted users only. [1]
- If upgrading is not immediately possible, administrators should consider auditing project role assignments and limiting
workflow:readaccess on sensitive workflows to users who should also be permitted to execute them. [1]
General practice, not from the source: if the affected software could read tokens or credentials, rotate them after upgrading; pin versions and review changes before updating tools your agents run.
What happened
Impact
- This could result in unintended outbound API calls, data mutations, or other side effects in downstream systems connected to the workflow. [1]
- This issue primarily affects instances where the Evaluations feature is in use and where users may have
workflow:readaccess withoutworkflow:executeaccess, such as deployments using RBAC project roles. [1]
