CRITICAL: Remove endpoint exposing sensitive credentials.
This endpoint poses a severe security risk by exposing:
-
Database credentials
-
Server configuration
-
MongoDB credentials
-
Remove this endpoint immediately:

🛠️ Refactor suggestion
Enhance database connection handling.
The current implementation lacks proper error handling and connection management.
Consider implementing:
- Connection pooling
- Error handling with proper exception catching
- Connection timeout settings
def get_db_connection():
- conn = sqlite3.connect(DATABASE)
- return conn
+ try:
+ conn = sqlite3.connect(
+ DATABASE,
+ timeout=30,
+ check_same_thread=False
+ )
+ return conn
+ except sqlite3.Error as e:
+ app.logger.error(f"Database connection error: {e}")
+ raise📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

CRITICAL: Fix SQL injection vulnerability immediately.
The current implementation is vulnerable to SQL injection attacks through raw string concatenation. This is a severe security risk that could allow attackers to:
- Access unauthorized data
- Modify database contents
- Execute arbitrary commands
Apply this fix immediately by uncommenting the secure implementation and removing the vulnerable code:
- # Vulnerable SQL Query from raw string concatenation
- query = f"SELECT * FROM users WHERE name = '{name}'"
- cursor.execute(query)
+ # Secure SQL Query using parameterized queries
+ query = "SELECT * FROM users WHERE name = ?"
+ cursor.execute(query, (name,))Additionally, add input validation:
def get_user():
name = request.args.get('name')
+ if not name or not isinstance(name, str):
+ return jsonify({"error": "Invalid name parameter"}), 400

Security: Disable debug mode and restrict network binding.
Running with debug=True in production is a security risk as it can expose sensitive information and allow code execution through the debugger.
Modify the run configuration:
if __name__ == '__main__':
init_db() # Initialize the database and populate it
- app.run(host="0.0.0.0", debug=True)
+ debug_mode = os.getenv('FLASK_DEBUG', 'False').lower() == 'true'
+ app.run(
+ host="127.0.0.1", # Only bind to localhost unless explicitly needed
+ debug=debug_mode, # Control through environment variable
+ )📝 Committable suggestion
