AI Code Security: OWASP LLM Top 10, RAG Poisoning & Zero Trust
Series Orientation: This article is Part 5 of the AI Code Review & Vibe Coding series, presenting the security threat model for AI-generated code. For the automated review pipeline that runs these security checks, see Part 4 — Building the Review Pipeline. In 2025, security researchers introduced a metric that should permanently reshape how engineering teams think about AI-generated code: AI-assisted code exhibits 2.7× higher vulnerability density than carefully reviewed human-written code. Not because AI is uniquely incompetent at security — it is not — but because the patterns of failure are systematic, predictable, and concentrated in exactly the areas that automated detection is weakest. ...
