In order to instruct the grat binary to perform a decoding operation, the Node.js script must dynamically pass user provided arguments via the command line interface. This is a highly vulnerable vector. If raw, unsanitized user input (the base64 XDR string) is blindly concatenated and passed to the underlying operating system shell, it opens the application to devastating Command Injection vulnerabilities. Malicious actors could append shell operators (like a forced recursive delete command) to the payload. Even without malicious intent, if the XDR string contains unexpected special characters, the shell's argument parser may fracture the string, resulting in corrupted cryptographic inputs being delivered to the Rust engine.
Issues/what to fix
The script must implement an airtight argument orchestrator that extracts the target XDR string directly from the process arguments (process.argv[2]). Before execution, it must validate that the extracted string strictly conforms to base64 encoding heuristics (using a comprehensive Regular Expression), rejecting invalid formats outright. Most importantly, the execution logic must categorically avoid using child_process.exec (which spawns a dangerous shell environment) and instead rely strictly on execFile, passing the command arguments as a strictly defined, immutable Array: ['decode', validatedXdrString, 'format', 'json']. This absolutely bypasses shell interpolation, neutralizing all injection risks.

Expected result
The Node.js script will safely and securely ingest arbitrary user input, mathematically validate the cryptographic payload format, and securely pass the data to the Rust engine isolated from the system shell, eliminating all command injection and parsing vulnerabilities.
