  message: >-
    Detected a `$IMPORT` SQL statement that comes from a function argument. This could lead to SQL injection
    if the variable is user-controlled and is not
    properly sanitized. In order to prevent SQL injection, it is recommended to
    use parameterized queries or prepared statements.
