The API_TOKEN is hardcoded directly in the source code. This is a critical security vulnerability as API tokens are exposed in version control. An attacker can use this token to impersonate the application and gain unauthorized access to protected resources.
+ Move the API token to environment variables or a secure secrets management system. Use os.getenv('API_TOKEN') to retrieve the value at runtime, and ensure tokens are never committed to version control.

The SECRET_KEY is hardcoded directly in the source code. This is a critical security vulnerability as the secret key is exposed in version control and can be easily discovered by anyone with access to the repository. Hardcoded secrets can lead to authentication bypass and unauthorized access.
+ Move all secrets to environment variables or a secure secrets management system. Use os.getenv('SECRET_KEY') to retrieve the value at runtime, and ensure the .env file or secrets manager is never committed to version control.

The database password is hardcoded directly in the source code. This is a critical security vulnerability as database credentials are exposed in version control. An attacker with access to the repository can directly access the database and compromise all user data.
+ Move the database password to environment variables or a secure secrets management system. Use os.getenv('DB_PASSWORD') to retrieve the value at runtime, and ensure credentials are never committed to version control.

The login() function constructs SQL queries using string interpolation (f-string) with unsanitized user input. An attacker can inject arbitrary SQL code through the username or password parameters. For example, an attacker could use username="' OR '1'='1" to bypass authentication and access any user account.
+ Use parameterized queries (prepared statements) instead of string interpolation. Replace the query construction with: cursor.execute("SELECT * FROM users WHERE username=? AND password=?", (username, password))

The get_user_data() function constructs SQL queries using string interpolation (f-string) with unsanitized user_id parameter. An attacker can inject arbitrary SQL code through the user_id parameter, potentially accessing unauthorized data or modifying the database.
+ Use parameterized queries (prepared statements) instead of string interpolation. Replace the query with: cursor.execute("SELECT * FROM users WHERE id = ?", (user_id,))

The hash_password() function uses MD5 for password hashing. MD5 is cryptographically broken and unsuitable for further use. It is fast to compute, making it vulnerable to brute-force attacks. Additionally, MD5 does not use salt, making rainbow table attacks possible. Passwords should never be hashed with MD5.
+ Use a modern, secure password hashing algorithm such as bcrypt, scrypt, or Argon2. For example, use the 'bcrypt' library: import bcrypt; bcrypt.hashpw(password.encode(), bcrypt.gensalt())

The authenticate() function performs a simple string comparison of the token without any rate limiting, token expiration, or secure comparison. This is vulnerable to timing attacks and brute-force attacks. Additionally, the token is compared using plain equality (==) which is vulnerable to timing attacks.
+ Use constant-time comparison (hmac.compare_digest) to prevent timing attacks. Implement rate limiting, token expiration, and proper token validation. Consider using industry-standard authentication mechanisms like JWT with proper validation.
