The project uses Zod for input validation, which is a good practice. API keys are managed via environment variables and a multi-key polling mechanism, and proxy endpoints are protected by signature verification (`ACCESS_PASSWORD`). However, the `/api/crawler` endpoint, when authenticated, allows the server to fetch an arbitrary URL provided in the request body, which poses a Server-Side Request Forgery (SSRF) risk if the `ACCESS_PASSWORD` is compromised. Additionally, processing user-uploaded files (Office, PDF) introduces potential attack surface for parsing vulnerabilities. Interactions with LLMs are susceptible to prompt injection attacks, a general risk in AI applications. The security of the application heavily relies on the secrecy of `ACCESS_PASSWORD` and the robustness of third-party libraries used for file parsing and AI SDKs.
