  • InfoAS-010

    🔑Insecure Secret Handling

    authenticate:input parameter "token" accepts a credential (informational; not evidence of insecure handling)

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.
