myTRS Code Review Action Plan

Executive Summary

This document outlines a comprehensive action plan to address code quality issues identified in the myTRS codebase review conducted on 2025-08-21. The plan is organized into four phases, prioritizing critical security issues and high-impact improvements.

Overall Quality Score: 7.2/10 � Target: 9.0/10

Phase 1: Critical Security & Code Consolidation (Weeks 1-2)

1.1 Security Vulnerabilities Remediation

Task: Fix Command Injection in Build Scripts

Status: � Pending
Owner: Security Team
Sub-agent: security-auditor

Checklist:

Audit fix-tag-final.js for command injection vulnerabilities
Replace direct shell command execution with safe alternatives
Add input validation for all user-provided paths
Implement path sanitization utilities
Add security tests for build scripts

Implementation:

// Before (VULNERABLE - fix-tag-final.js lines 12-21)
const command = platform === 'win32' 
  ? `powershell -Command "Get-Content '${inputFile}' | Set-Content '${outputFile}' -Encoding UTF8"`
  : `iconv -f ISO-8859-1 -t UTF-8 '${inputFile}' > '${outputFile}'`;
exec(command, callback);

// After (SECURE)
const { spawn } = require('child_process');
const path = require('path');

function safeFileConversion(inputFile, outputFile) {
  // Validate and sanitize paths
  const safeinput = path.resolve(path.normalize(inputFile));
  const safeOutput = path.resolve(path.normalize(outputFile));
  
  // Validate paths are within project directory
  const projectRoot = path.resolve(__dirname, '..');
  if (!safeinput.startsWith(projectRoot) || !safeOutput.startsWith(projectRoot)) {
    throw new Error('Path traversal attempt detected');
  }
  
  // Use spawn instead of exec for safety
  if (platform === 'win32') {
    return spawn('powershell', [
      '-Command',
      'Get-Content',
      '-Path', safeinput,
      '|',
      'Set-Content',
      '-Path', safeOutput,
      '-Encoding', 'UTF8'
    ], { shell: false });
  } else {
    return spawn('iconv', [
      '-f', 'ISO-8859-1',
      '-t', 'UTF-8',
      safeinput
    ], { 
      shell: false,
      stdio: ['pipe', fs.createWriteStream(safeOutput), 'pipe']
    });
  }
}
