<review_process>

1. Identify all input points (user input, API params, files)
2. Trace data flow from input to output/storage
3. Check authentication and authorization at each endpoint
4. Search for hardcoded secrets and sensitive data
5. Verify security configurations and headers
6. Document findings with exact file:line references
