Pull Request Overview
This PR successfully adds a security headers middleware to the FastAPI application. Key recommendations include refactoring to a pure ASGI middleware to avoid performance overhead and moving hardcoded security policies into the application configuration.

🟡 MEDIUM RISK
Suggestion: The Content-Security-Policy values are currently hardcoded in the middleware. It is a best practice to move these to your configuration settings (e.g., in backend/core/config.py) to allow for environment-specific adjustments without changing source code.\n\nTry running the following prompt in your IDE agent:\n> Move the hardcoded CSP and other security header values from security_middleware.py to the application settings in config.py and update the middleware to use them.

| """ | ||
| Middleware that adds security headers to all HTTP responses. | ||
|
|
||
| This middleware should be added to the FastAPI application to ensure | ||
| all responses include appropriate security headers that protect against | ||
| common web vulnerabilities. | ||
|
|
||
| Example: | ||
| app = FastAPI() | ||
| app.add_middleware(SecurityHeadersMiddleware) | ||

🟡 MEDIUM RISK
Suggestion: Using BaseHTTPMiddleware can introduce performance overhead and potential issues with background tasks in FastAPI. For a middleware that only adds headers, a pure ASGI implementation is more efficient.\n\nTry running the following prompt in your IDE agent:\n> Rewrite the SecurityHeadersMiddleware class in backend/core/security_middleware.py using the pure ASGI interface (call(self, scope, receive, send)) to add security headers directly to the response.

⚪ LOW RISK
Suggestion: Consider adding the preload directive to your Strict-Transport-Security header to allow inclusion in browser HSTS preload lists.\n\nThis might be a simple fix:\nsuggestion\n response.headers["Strict-Transport-Security"] = (\n "max-age=31536000; includeSubDomains; preload"\n )\n
Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.
