AI coding tools generate code that works — that's their strength. But working code is not necessarily secure code. AI models are trained on vast amounts of code, including code with security vulnerabilities. They learn patterns, and the patterns they generate often include common security antipatterns.
1. Hardcoded credentials AI often includes credentials, API keys, or passwords directly in code for simplicity:
api_key = "sk-abc123..." # This is in the code for everyone to read
If this code is shared or pushed to a public repository, the credentials are compromised.
2. SQL injection vulnerabilities AI tools frequently generate database queries that directly interpolate user input — a classic and dangerous vulnerability:
query = f"SELECT * FROM users WHERE name = '{user_input}'" # Dangerous!
An attacker can craft input that manipulates the database query.
3. Missing authentication AI-generated web apps often run endpoints without requiring users to prove who they are. Any user can access any data.
4. Exposed sensitive data AI may generate APIs that return full database records including fields that should not be public (passwords, internal IDs, private metadata).
5. Absent input validation AI-generated code often trusts user input completely, allowing unexpected inputs to crash the system or manipulate behavior.
