Fix code scanning alert no. 5: Missing rate limiting

[RectiFlex]

Fixes https://github.com/RectiFlex/AI_CO_FOUNDER/security/code-scanning/5

To fix the problem, we need to apply the existing rate limiter middleware to the /api/documents endpoint. This will ensure that the endpoint is protected against denial-of-service attacks by limiting the number of requests that can be made in a given time window.

• We will add the limiter middleware to the /api/documents endpoint.
• This change will be made in the api/index.ts file.
• No new methods or definitions are needed, as the limiter middleware is already defined and imported.

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

PR summary

This Pull Request addresses a security vulnerability identified as a missing rate limiting issue on the /api/documents endpoint. By adding the existing limiter middleware to this endpoint, the PR aims to protect the application from potential denial-of-service attacks by restricting the number of requests that can be made within a specified time frame. The change is implemented in the api/index.ts file, leveraging already defined and imported middleware, thus requiring no additional methods or definitions.

Suggestion

Ensure that the rate limiting parameters (such as the maximum number of requests and the time window) are appropriately configured to balance security and user experience. Additionally, consider documenting the rate limiting policy for users to understand the limitations and avoid unintended blocking.
