The code contains a high-impact security risk: handleUploadFile allows a caller to supply file_path, which the server uses to read arbitrary local files and upload them externally via an OSS-signed HTTP POST. This can act as a server-side exfiltration primitive if the MCP caller/authorization is not strictly controlled. Additionally, it may leak upstream error response bodies via logs. No clear obfuscation or explicit malware (e.g., backdoor/reverse shell) is present in this fragment, but the file read/upload behavior warrants strict access control and path allowlisting/sandboxing.
