The most common flaws include missing input sanitization, hardcoded credentials, over-permissive IAM defaults, hallucinated dependencies, and incomplete access control. Real CVE incidents from Lovable, Cursor, and a fully vibe-coded social platform illustrate the real-world impact. The author explains why AI models are structurally poor at security (optimized for functional correctness, lack adversarial reasoning, trained on insecure examples) and shares a practical review checklist: read every line, run SAST on every PR, verify all imports, audit auth separately, check env variable handling, use AI to review AI output, and keep a vulnerability log. A warning is raised about junior developers using AI tools without the security judgment to review outputs, and about organizations cutting senior engineers who provide that review capacity. ## Full article daily.dev links to this article rather than hosting it.
