Security suggestion: Potential eval() usage in optimization pipeline

[Fujun-0807]

Hi @codeflash-ai team,

Big fan of your code optimization approach! I've been following the project and love the concept of AI-powered code optimization.

🔍 Security Observation

I noticed some areas where eval() or dynamic code execution might be used in the optimization pipeline. While I understand this might be necessary for your use case, here are some suggestions:

Recommendations

1. Sandboxing – If eval() is necessary, consider using restricted globals:

   eval(code, {"__builtins__": {}}, safe_locals)

2. Timeout protection – Add execution timeouts to prevent infinite loops

3. Input validation – Sanitize any user-provided code before execution

🛠️ Tool Used

I built Code Guardian – a minimalist code review tool focused on security and common bugs. It flagged some patterns in the codebase that might benefit from review.

Potential Collaboration?

I wonder if there might be synergy between our projects:

• Code Guardian as a pre-processor for security checks
• Before CodeFlash optimizes code, ensure it's secure

Would love to explore if there's potential for integration!

Cheers,
