AIR-001critical SeverityAI-Generated Anti-Patterns & Dynamic Execution

No eval() or new Function() Dynamic Execution Sinks

When asked to parse dynamic expressions or formulas, AI code resorts to eval() or new Function(code)() which creates arbitrary code execution holes.

Review my codebase for "No eval() or new Function() Dynamic Execution Sinks" (AIR-001).
Issue: When asked to parse dynamic expressions or formulas, AI code resorts to eval() or new Function(code)() which creates arbitrary code execution holes.
Remediation required: Use a safe, sandboxed expression evaluator (such as mathjs or a dedicated AST parser) instead of eval().

Please:
1. Locate any occurrences of this issue across my repository.
2. Refactor the code to follow production standards without breaking existing functionality.
3. Provide a clear command or step to test and verify the fix.

Why AI Assistants Write This Bug

When asked to parse dynamic expressions or formulas, AI code resorts to eval() or new Function(code)() which creates arbitrary code execution holes.

AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.

Remediation & Verification Checklist

Remediation: Use a safe, sandboxed expression evaluator (such as mathjs or a dedicated AST parser) instead of eval().
  1. Search your codebase for pattern matching "No eval() or new Function() Dynamic Execution Sinks".
  2. Apply the recommended remediation: Use a safe, sandboxed expression evaluator (such as mathjs or a dedicated AST parser) instead of eval().
  3. Run local build and test commands to ensure no regressions.
  4. Verify in your browser or with curl that the issue is resolved.
