Claude Code produces some of the strongest AI-written code available, often cleaner than a hand-rolled first draft. The point of a scan is not that the code is bad. It is that security review is a separate job, and an agent focused on making a feature work is not simultaneously auditing it against the ways AI code tends to fail.
What still slips through
- Missing authorization on generated routes, including Broken Object Level Authorization
- Hardcoded secrets in scaffolding, migrations, or config
- Fallback secrets in environment lookups that become predictable in production
- JWTs decoded without verifying, and Supabase access without Row Level Security
We measured this across model generations: the secret-leak rate held roughly flat, because the flaw is a pattern of the task, not a gap in the model. The data is in the Claude models security comparison.
