Fix code scanning alert no. 3: Missing rate limiting

[RectiFlex]

Fixes https://github.com/RectiFlex/AI_CO_FOUNDER/security/code-scanning/3

To fix the problem, we need to apply the rate limiter to the routes that perform sensitive operations, such as creating, fetching, and updating ideas. This can be done by adding the rate limiter middleware to these routes. The rate limiter has already been defined in the code, so we just need to apply it to the relevant routes.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.

PR summary

This Pull Request addresses a code scanning alert related to missing rate limiting on certain API routes. The purpose is to enhance security by preventing abuse of the /api/ideas endpoints, which handle sensitive operations like creating, fetching, and updating ideas. The rate limiter middleware, already defined in the codebase, is applied to these routes to control the number of requests a user can make in a given timeframe. This change helps mitigate potential denial-of-service attacks and ensures fair usage of the API.

Suggestion

Consider adding tests to verify that the rate limiting is functioning as expected. This could include tests to ensure that requests exceeding the limit are properly throttled and that legitimate requests within the limit are processed correctly. Additionally, documenting the rate limits in the API documentation would be beneficial for users to understand the constraints.

Hey @RectiFlex - I've reviewed your changes and found some issues that need to be addressed.

Blocking issues:

• Rate limiter middleware should be consistently placed before authentication across all endpoints (link)

Overall Comments:

• Consider placing the rate limiter middleware consistently before authentication across all routes to prevent potential DOS attacks on the authentication system

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🔴 Security: 1 blocking issue
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
• 🟢 Documentation: all looks good

🚨 issue (security): Rate limiter middleware should be consistently placed before authentication across all endpoints

Currently, the rate limiter placement is inconsistent across endpoints. To prevent DoS attacks and ensure proper rate limiting, the limiter should always be applied before authentication checks.
