| Description | The affected component is `application/PHP/objects/notes/search_scratch_data.php`, which passes the user-controlled `field_name` parameter into `Notes_controller::search_scratch_data()`. The controller concatenates `field_name` into the SQL structure three times:
```php
$field_name = $_POST["field_name"];
...
$select_statement = $this->db_holder->prepare("SELECT sd.* FROM scratch_data AS sd, users_scratch_data AS usd, users AS u WHERE sd.scratch_data_id = usd.scratch_data_id AND u.user_id = usd.user_id AND u.user_id = ? AND (".$field_name." LIKE ? OR ".$field_name." LIKE ? OR ".$field_name." LIKE ?) ORDER BY date_added, time_added ASC;");
$select_statement->execute(array($_SESSION["user_id"], "%".$value, "%".$value."%", $value."%"));
```
An authenticated attacker can inject SQL expressions such as `scratch_data) OR SLEEP(1) OR (scratch_data` through `field_name`, causing measurable database delays. This is a blind SQL injection that can be used to infer database contents.
