If you’re building with Cursor, you already know it’s good at producing working code quickly. What it doesn’t do is reason about security unless you explicitly ask, and most people don’t, because the feature works and shipping feels done.
What Cursor tends to miss
- Hardcoded credentials in migration files and seed scripts
- SQL/NoSQL injection from string-concatenated queries in fast-written auth code
- Missing authentication on newly scaffolded CRUD routes
- BOLA: auth checks that confirm login but not ownership
- Fallback secrets in config files generated during setup

How Prbl fits into a Cursor workflow
Paste your repo URL for a free scan, or wire Prbl into your GitHub Action so every PR, including the ones Cursor wrote most of, gets checked automatically before merge. Findings link directly to the file and line, the same way Cursor’s own diff view does, so fixing them fits the workflow you’re already in.
The honest pitch
Prbl doesn’t replace reviewing Cursor’s output. It catches the specific, repeatable mistakes that reviewing for “does this work” tends to miss, because those mistakes still compile, still pass the obvious tests, and still look like clean code.
Frequently asked questions
Does Cursor review its own code for security?
No, not unless you explicitly ask, and most people don't because the feature works and shipping feels done.
Can Prbl run automatically on every Cursor-generated pull request?
Yes. Wire Prbl into your GitHub Action and every PR, including the ones Cursor wrote most of, gets checked automatically before merge.
What specifically does Cursor tend to miss?
Hardcoded credentials in migration and seed files, SQL/NoSQL injection from string-concatenated queries, missing authentication on newly scaffolded CRUD routes, BOLA, and fallback secrets in generated config.
