# EasyStream - Missing Features & Critical Gaps Analysis

## Executive Summary

EasyStream is a sophisticated video streaming platform with **1000+ PHP files** and strong Docker infrastructure. However, it has **25+ critical gaps** that need addressing before production deployment. This document prioritizes what's missing and provides implementation guidance.

**Overall Maturity:** 70% (Solid foundation, needs production hardening)

---

## 🚨 CRITICAL PRIORITIES (Deploy Within 1-2 Weeks)

### 1. Security Headers ⚠️ IMMEDIATE
**Status:** ❌ NOT IMPLEMENTED
**Risk Level:** CRITICAL
**Estimated Time:** 2-4 hours

**Missing Headers:**
- Content-Security-Policy (CSP) - Prevents XSS attacks
- X-Frame-Options - Prevents clickjacking
- Strict-Transport-Security (HSTS) - Forces HTTPS
- X-Content-Type-Options - Prevents MIME sniffing
- Permissions-Policy - Restricts browser features

**Impact:** Currently vulnerable to XSS, clickjacking, MIME-type attacks

**Quick Fix:**
```php
// Add to config.core.php
require_once 'f_core/config.security.php';
```

**File to Create:** `f_core/config.security.php` (template provided in previous conversation)

---

### 2. File Upload Vulnerabilities ⚠️ CRITICAL
**Status:** ⚠️ PARTIALLY MITIGATED
**Risk Level:** CRITICAL
**Estimated Time:** 6-8 hours

**Current Issues:**

- No magic byte verification
- No virus scanning
- Filename not properly sanitized
- No upload rate limiting

**Found In:**
- `upload.php` (lines 20-45)
- Various API upload endpoints
