+
+## 🛠️ Remediation Plan
+
+### Immediate Actions (High Priority)
+
+#### 1. Update Vulnerable Dependencies
+
+```bash
+# Update to secure versions
+pip install --upgrade werkzeug>=3.0.6
+pip install --upgrade jinja2>=3.1.5
+pip install --upgrade flask>=3.1.1
+pip install --upgrade ecdsa>=0.20.0
+pip install --upgrade python-jose>=3.6.0
+```
+
+#### 2. Fix Code Formatting
+
+```bash
+# Apply automatic formatting
+black .
+isort .
+```
+
+#### 3. Add Type Annotations
+
+Priority files to fix:
+- `main.py`: 25 type annotation errors
+- `src/web/app.py`: 20 type annotation errors
+
+Example fixes:
+```python
+# Before
+def process_measurement(self, data):
+    # ...
+
+# After
+def process_measurement(self, data: dict) -> None:
+    # ...
+```
+
+### Medium Priority Actions
+
+#### 1. Remove Unused Imports
+
+Files with unused imports:
+- `main.py`: 10 unused imports

+
+## 🔒 Security Recommendations
+
+### 1. Input Validation
+
+```python
+# Add input validation for all user inputs
+from flask import request
+import re
+
+def validate_filename(filename: str) -> bool:
+    """Validate uploaded filename"""
+    return bool(re.match(r'^[a-zA-Z0-9._-]+\.csv$', filename))
+```
+
+### 2. Security Headers
+
+```python
+# Add security headers to Flask app
+from flask import Flask
+
+app = Flask(__name__)
+
+@app.after_request
+def add_security_headers(response):
+    response.headers['X-Content-Type-Options'] = 'nosniff'
+    response.headers['X-Frame-Options'] = 'DENY'
+    response.headers['X-XSS-Protection'] = '1; mode=block'
+    return response
+```
+
+### 3. Environment Variables
+
+```python
+# Use environment variables for sensitive data
+import os
+from dotenv import load_dotenv
+
+load_dotenv()
+
+SECRET_KEY = os.getenv('SECRET_KEY')
+DATABASE_URL = os.getenv('DATABASE_URL')
+```
