A severe path traversal vulnerability exists in its backend API endpoints, specifically `/deploy/fileDiff` (File Compare), when handling file paths provided by the client. The original logic of this endpoint is to read a local project file and compare it with a file on a remote target server. However, due to insufficient validation and sanitization of the `filePath` parameter, and the lack of security constraints on the final absolute file path, malicious paths containing `../` are directly executed within the system. This leads to a **dual arbitrary file read** issue: 1. **Local Host File Read**: `os.ReadFile` is tricked by the directory traversal payload to read any file via its absolute path on the Goploy local host (returned in the `srcText` field of the response body). 2. **Remote Controlled Server File Read**: Subsequently, the same payload is utilized via the SFTP protocol on the target server pointed to by the `serverID`. Influenced similarly by the directory traversal, it reads any file on the configured remote server (returned in the `distText` field of the response body). **The threshold for exploiting this vulnerability is extremely low, and the conditions are v",
