Security Upgrade Review: ESLint 8.6.0 → 9.0.0

This Snyk-generated PR addresses important security vulnerabilities by upgrading ESLint, but requires additional changes to prevent breaking the application.

✅ Security Benefits

• Fixes ReDoS vulnerability in cross-spawn (SNYK-JS-CROSSSPAWN-8303230, Score: 169)
• Fixes ReDoS vulnerability in brace-expansion (SNYK-JS-BRACEEXPANSION-9789073, Score: 57)

⚠️ Critical Issues Requiring Action

1. Dependency Compatibility: The TypeScript ESLint packages (@typescript-eslint/eslint-plugin@^5.9.0 and @typescript-eslint/parser@^5.9.0) are incompatible with ESLint v9 and will cause runtime failures
2. Breaking Changes: ESLint v9 introduces significant breaking changes including flat config requirements and Node.js version constraints

🔧 Required Actions Before Merge

1. Update TypeScript ESLint packages to v8.x for ESLint v9 compatibility
2. Test thoroughly in a staging environment to ensure the GitHub Action still functions correctly
3. Consider updating TypeScript from v4.5.4 to v5.x for better compatibility
4. Verify Node.js version meets ESLint v9 requirements (18.18.0+)

Recommendation

Do not merge as-is. Apply the suggested dependency updates first, then test the complete GitHub Action workflow to ensure ESLint functionality remains intact after the major version upgrade.

[amazon-q-developer]

⚠️ Breaking Change Risk: This ESLint upgrade from v8.6.0 to v9.0.0 is a major version jump that introduces significant breaking changes. ESLint v9 includes new configuration format requirements (flat config), rule changes, and Node.js version requirements that may cause compatibility issues with the current TypeScript ESLint plugins and existing configurations.

[amazon-q-developer]

🛑 Dependency Compatibility Issue: The TypeScript ESLint packages (@typescript-eslint/eslint-plugin@^5.9.0 and @typescript-eslint/parser@^5.9.0) are severely outdated and incompatible with ESLint v9. These v5 packages only support ESLint v6-8, which will cause runtime errors and prevent the linting functionality from working.

Suggested change

	"dependencies": {
	"@typescript-eslint/eslint-plugin": "^5.9.0",
	"@typescript-eslint/parser": "^5.9.0",
	"eslint": "^8.6.0",
	"eslint": "^9.0.0",
	"typescript": "^4.5.4"
	},
	"dependencies": {
	"@typescript-eslint/eslint-plugin": "^8.0.0",
	"@typescript-eslint/parser": "^8.0.0",
	"eslint": "^9.0.0",
	"typescript": "^4.5.4"
	},

[amazon-q-developer]

The TypeScript version (^4.5.4) is also quite outdated and may have compatibility issues with the newer ESLint and TypeScript ESLint packages. Consider upgrading to TypeScript ^5.0.0 or later for better compatibility and access to newer language features.
