rules:
- id: gorm-dangerous-method-usage
  message: >-
    Detected usage of dangerous method $METHOD which does not escape inputs (see link in references).
    If the argument is user-controlled, this can lead to SQL injection. When using $METHOD function,
    do not trust user-submitted data and only allow approved list of input (possibly, use an allowlist
    approach).
