n8n before 1.123.85, 2.43.5, and 2.44.1 Credential Exposure via Node Execution Error Data

Summary

n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 stores credential secrets in execution error data when operations fail in the Git, MongoDB Atlas Vector Store, and Google Cloud Storage nodes. Users who can view a workflow's executions but cannot read the credential can recover Git passwords or tokens, MongoDB database passwords, or Google access tokens from that data.

Remediation

1. Inventory every n8n-io n8n deployment, including staging.
2. Upgrade n8n-io n8n to the fixed version for your release line, listed under Affected versions.
3. Confirm the running version after the upgrade.
