  • InfoAS-010

    🔑Insecure Secret Handling ×2

    input parameter "skip_token" accepts a credential (informational; not evidence of insecure handling)

    OUTLOOK_GET_MAIL_DELTA

    input parameter "delta_token" accepts a credential (informational; not evidence of insecure handling)

    OUTLOOK_GET_MAIL_DELTA

    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.
