Review My Code for Bugs and Issues

Review the following code and provide a thorough analysis:

```
[paste your code here]
```

Language / framework: [e.g. TypeScript / React / Python / Go]
Context: [what this code is supposed to do]
Your main concern: [e.g. performance / security / correctness / readability]

Review for:
1. Bugs or logical errors (flag as CRITICAL / MAJOR / MINOR)
2. Security vulnerabilities (e.g. injection risks, exposed secrets, auth issues)
3. Performance problems (unnecessary re-renders, N+1 queries, blocking operations)
4. Code smells (overly complex logic, poor naming, missing error handling)
5. Missing edge cases

For each issue found:
- Describe the problem clearly
- Show the problematic code snippet
- Provide a corrected version with explanation

At the end, give an overall quality score (1–10) and the top 3 things to fix first.
