Security Blind Spots in AI‑Generated Code

Introduction AI models are trained on vast amounts of public code, which often includes insecure practices. Without careful prompting and review, AI can introduce critical security vulnerabilities. This post covers five common security mistakes and how to avoid them. Mistake 1: AI‑Generated Hardcoded Secrets Description: AI includes hardcoded API keys, passwords, or tokens in generated code. Realistic Scenario: AI generates AWS S3 client code with hardcoded access keys in the example. ❌ Wrong Prompt: Write code to upload file to S3 ⚠️ Why it is wrong: AI may generate aws_access_key_id = "AKIAIOSFODNN7EXAMPLE" which developers might not replace. ✅ Better Prompt: Write code to upload file to S3 using AWS SDK v2. Security requirements: NEVER hardcode credentials Use DefaultCredentialsProvider (IAM roles in production) For local dev, use environment variables or ~/.aws/credentials Include comment that credentials must never be committed to repo Use IAM roles with least privilege principle
