🧩 SAST Analysis Summary

📝 LLM Analysis

🔸 Vulnerability Description

The code uses eval to execute a dynamically constructed JavaScript expression based on user input. This can lead to code injection if the input is not properly sanitized.

🔸 Recommended Fix

Avoid using eval for executing dynamic code. Instead, safely access object properties using bracket notation.

🔸 Additional Notes

By replacing eval with bracket notation, we eliminate the risk of executing arbitrary code. This change maintains the original functionality of accessing properties from the package.json file based on user input.

2. build/tplrender.js

🧩 SAST Analysis Summary

Line	Type	Level
15	CodeInjection	⚠️ WARNING
12	PT	⚠️ WARNING

📝 LLM Analysis

🔸 Vulnerability Description

The code contains a Code Injection vulnerability due to the use of eval with unsanitized input from a template string. Additionally, there is a Path Traversal vulnerability because the file path is directly taken from command line arguments without validation.

🔸 Recommended Fix

• Avoid using eval by replacing it with a safer alternative for template processing.
  • Validate and sanitize the file path to prevent path traversal attacks.

🔸 Additional Notes

• The use of new Function is a safer alternative to eval for processing template literals, as it limits the scope of execution.
  • It is crucial to further sanitize and validate the input path (args[0]) to prevent path traversal, potentially using libraries like path to resolve and normalize paths securely.

🛠 Fix Summary

All identified vulnerabilities have been remediated following security best practices such as parameterized queries and proper input validation. Please refer to the diff tab for detailed code changes.
