Gemini 3.5 Flash vs Grok 4.5 for code review

Here is the review of the Express route, ranking the defects by severity, explaining their behavior, and providing the corrected code.

### Defect 1: SQL Injection (Severity: High)

#### Description
The route directly interpolates the `status` query parameter into the SQL string using template literals (`'${status}'`). This allows untrusted user input to alter the structure of the SQL command executed by the database.

#### Example Exploit Input
An attacker could supply the following value for the `status` parameter in the query string:
``…

## Defects (by severity)

### 1. **Critical — SQL injection**
`status` is concatenated into the SQL string. An attacker controls the query.

**Exploit example:**  
`GET /api/orders?status='%20OR%20'1'='1`

That yields:
```sql
SELECT id, customer, total FROM orders WHERE status = '' OR '1'='1' ORDER BY created_at DESC
```
→ returns **every order**.  
Worse payloads can read other tables, modify data, or drop tables (depending on DB privileges), e.g.  
`status='; DROP TABLE orders; --`

### 2. **High — missing `await` on a Promise**
