Official description

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.
