Expected Output

**Summary**: Function processes user data by evaluating input and transforming positive numbers.

**Strengths**: 
- Clear function name and simple logic
- Consistent code formatting

**Issues Found**:
- 🔴 **Critical - Security Vulnerability**: Using `eval()` on user input is extremely dangerous. This allows arbitrary code execution and opens severe security risks.

- 🟡 **Major - Missing Error Handling**: No validation for input types or handling of potential exceptions.

- 🟡 **Major - Type Hints**: Function lacks type annotations, making it harder to understand expected input/output types.

- 🔵 **Minor - Performance**: List comprehension would be more pythonic and efficient.

**Suggested Fix**:
```python
from typing import List
import json

def process_user_data(user_input: str) -> List[int]:
    """Process user data, doubling positive numbers."""
    try:
        # Use json.loads instead of eval for safety
        data = json.loads(user_input)
        if not isinstance(data, list):
            raise ValueError("Input must be a JSON array")
        
        # Use list comprehension for better performance
        return [item * 2 for item in data if isinstance(item, (int, float)) and item > 0]
    except (json.JSONDecodeError, ValueError) as e:
        raise ValueError(f"Invalid input format: {e}")
```

**Recommendation**: Request Changes - Critical security issue must be addressed before merging.
