express-rate-limitmiddleware is used to limit the number of requests from a single IP address, mitigating the risk of DoS attacks.req.body.searchis checked to ensure it is a string before processing, preventing unexpected types from causing issues.requireusage for market data is retained but should be carefully reviewed to ensure only safe paths are used.3.
scripts/sync.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code is vulnerable to Indirect Command Injection and Path Traversal vulnerabilities. Unsanitized input from command line arguments is used directly in
child_process.execSync,fs.appendFileSync,fs.readFileSync, andfs.unlinkSync, which can lead to command injection and path traversal attacks.🔸 Recommended Fix
Validate and sanitize all inputs derived from command line arguments before using them in sensitive operations like executing system commands or accessing the file system.
🔸 Additional Notes
The modifications ensure that inputs from command line arguments are validated and sanitized before being used in sensitive operations. This helps prevent potential security vulnerabilities related to command injection and path traversal.
