## Question

Review this Flask API endpoint for security vulnerabilities. Identify ALL security issues and explain the fix for each.

```python
from flask import Flask, request, jsonify

import pickle
import os

app = Flask(__name__)

@app.route('/api/user/<user_id>')
def get_user(user_id):
    conn = sqlite3.connect('users.db')
    cursor = conn.cursor()
    query = f"SELECT * FROM users WHERE id = {user_id}"
    cursor.execute(query)
    user = cursor.fetchone()
    return jsonify({"user": user})

@app.route('/api/upload', methods=['POST'])
def upload_file():
    file = request.files['file']
    filename = file.filename
    file.save(os.path.join('/uploads', filename))
    return jsonify({"status": "uploaded", "path": f"/uploads/{filename}"})

@app.route('/api/settings', methods=['POST'])
def update_settings():
    data = pickle.loads(request.data)
    # Process settings...
    return jsonify({"status": "updated"})

@app.route('/api/redirect')

## Methodology

- **10×10 Blind Peer Matrix:** All models answer the same question, then all models judge all responses.
- **5 Criteria:** Correctness, completeness, clarity, depth, usefulness (each scored 1–10).
- **Self-judgments excluded:** Models do not judge their own responses.
- **Weighted Score:** Composite of all 5 criteria.
