Why AI Assistants Write This Bug
AI coding tools render streaming model output directly into DOM nodes without filtering out malicious script injection from external prompts.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
