Code Review
This pull request significantly improves the application's security by removing hardcoded secrets and making configurations environment-specific. The updates to the test suite to accommodate these changes are also well-executed. My review includes several suggestions to further enhance security and robustness, primarily focusing on adopting safer defaults for CORS, ensuring critical environment variables are present at startup, and centralizing the loading of environment variables for better maintainability.

The application relies on LVT_SECRET_KEY for a critical function (authentication). If this environment variable is not set, os.getenv() will return None, causing authentication to fail silently, which can be difficult to debug. The application should fail fast at startup if this critical configuration is missing.

Defaulting to "*" for allow_origins is a security risk, as it allows any origin to make requests. A more secure approach is to default to an empty list, which denies all cross-origin requests unless LVT_ALLOWED_ORIGINS is explicitly configured. This follows the principle of 'fail-safe defaults'.

There was a problem hiding this comment.
Using * for LVT_ALLOWED_ORIGINS is overly permissive, even in an example file, as it encourages insecure configurations during development. It's better to provide a more realistic and secure example that developers can adapt, such as specifying local development origins.
LVT_ALLOWED_ORIGINS=http://localhost:3000,http://127.0.0.1:3000

| load_dotenv() |
There was a problem hiding this comment.
Calling load_dotenv() within a library or class module can lead to unexpected side effects and makes it harder to control the application's configuration. Environment loading should be handled once at the application's entry point (e.g., in main.py, where it is already being called) to ensure a single source of truth for configuration.

Dice fix |
I've reviewed the PR and the code. The term 'dice' does not appear in the modified code or the original codebase (except for a warning in a bash script). If you meant 'fix' in Spanish (dice fix = says fix), I have already addressed the hardcoded secrets and updated the test suite. If you meant something else, please let me know! |

This PR addresses a critical security vulnerability where the
SECRET_KEYused for HMAC authentication was hardcoded in the backend. It also improves the application's security posture by environmentalizing CORS origins and fixing a regression in the test suite that was causing integration tests to fail.Key changes:
