Why AI Assistants Write This Bug

AI reset password flows sometimes put reset tokens or user emails in GET query parameters, leaking them into referrer headers.

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.
