# Vulnerable: User input is directly concatenated into the SQL query

SQL query built from user-controlled sources High

This SQL query depends on a
user-provided value

To fix the SQL injection vulnerability, we should use parameterized queries provided by the sqlite3 library. This approach ensures that user input is properly escaped and handled by the database driver, preventing SQL injection attacks.

  • Replace the f-string SQL query with a parameterized query.
  • Use placeholders (?) in the SQL query and pass the user input as a parameter to the execute method.
  • This change should be made in the search function in the aa.py file.

Flask app is run in debug mode High

A Flask app appears to be run in debug mode. This may allow an attacker to run arbitrary code through the debugger.

To fix the problem, we need to ensure that the Flask application does not run in debug mode in a production environment. The best way to achieve this is to use an environment variable to control the debug mode. This way, we can enable debug mode during development and disable it in production without changing the code.

  1. Import the os module to access environment variables.
  2. Modify the app.run() method to set the debug parameter based on an environment variable.
