The server relies on a hardcoded external IP address (106.15.125.133) for its backend services. While this is an intentional architectural choice to solve WeChat's IP whitelist requirement and the project includes a disclaimer for research use only, it introduces a critical dependency on the security and availability of that specific external server. If the external server were compromised or its IP repurposed, sensitive `AppID`, `AppSecret`, and `access_token` could be exposed. No 'eval', 'exec', or direct OS command injection vulnerabilities were found in the provided source code, and JSON payloads are handled by the `requests` library which typically provides serialization safety. Input parameters are obtained using `.get()` methods, which is safer than direct dictionary access.
