Security Vulnerability: GraphQL Introspection and Playground Enabled in Production - CWE-200

Overview

This PR implements Security Vulnerability: GraphQL Introspection and Playground Enabled in Production - CWE-200 based on the approved design document.

Issue: #214

Implementation Summary

Phase 1: Introduce Environment Guards in GraphQL Factory

• Added isProduction flag derived from NODE_ENV to guard GraphQL features
• Normalized GRAPHQL_PLAYGROUND and GRAPHQL_INTROSPECTION to strict booleans
• Ensured playground and introspection remain disabled whenever production mode is detected
• Commit: 93b98fe

Phase 2: Sanity Review & Formatting

• Introduced a helper for boolean parsing to keep the factory readable
• Reordered local constants for clarity and applied light formatting adjustments
• Commit: 33e5aee

Testing

• ✅ Comprehensive tests written for all new functionality (coverage for production/non-production toggles and parsing edge cases)
• ✅ All tests passing (9 suites, 37 tests)
• ✅ Test coverage meets project standards

Validation

• ✅ Lint checks passed
• ✅ Format checks passed
• ✅ Code quality verified (GraphQL config defaults reviewed)

Files Changed

• Total Commits: 4
• Implementation Commits: 2
• Test Commit: 1
• Validation Commit: 1

Review Notes

• GraphQL Playground and introspection cannot be enabled in production unless NODE_ENV is set to something other than production; confirm deployment environments are configured accordingly.
• Boolean parsing helper treats any value other than the string "true" (case-insensitive) as false, aligning with security expectations.

Implementation complete and ready for review.
