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

Impact

n8n versions before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 store credential secrets in execution error data when operations fail in certain nodes. Users who can view workflow executions may recover credentials.

Original source 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.
