What CodeShield finds.

Before — AI-Generated
# Classic vibe-coded Python
import sqlite3
import requests
 
DB_PASSWORD = "super_secret_123"
API_KEY = "ghp_abc123xyz789"
 
def get_user(username):
  conn = sqlite3.connect("users.db")
  q = "SELECT * FROM users WHERE username = '" + username + "'"
  cursor.execute(q) # SQL injection
 
def process(data):
  result = eval(data) # dangerous
  except: # bare except
    print("Error") # no logging
After — Production-Ready
import sqlite3, logging
import requests
from os import environ
 
DB_PASSWORD = environ.get("DB_PASSWORD")
API_KEY = environ.get("API_KEY")
 
def get_user(username: str) -> dict | None:
  with sqlite3.connect("users.db") as conn:
    cursor.execute("SELECT * FROM users WHERE username=?", (username,))
 
def process(data: str) -> float | None:
  result = ast.literal_eval(data)
  except ValueError as e:
    logging.error("Parse failed: %s", e)

Perf.
Critical SQL Injection via string concatenation — CWE-89. Fixed with parameterized queries.
Critical Hardcoded credentials in source — CWE-798. Moved to environment variables.
Critical eval() on user input — CWE-95. Replaced with ast.literal_eval().
Warning Bare except clause swallows all errors. Replaced with specific ValueError handling + logging.
