Randall Stillwell f408e151c8 🔒 CRITICAL SECURITY FIX: Implement Proper User Data Isolation ... 🚨 Fixed Major Data Leakage Issues: - Replaced hardcoded user_id = 1 with proper JWT authentication - Fixed collections API to filter by authenticated user - Fixed card ownership to use user_cards table (not global cards table) - Fixed decks API to return only user-owned decks - Fixed card collections/decks APIs to respect user permissions - Fixed favorites API to use user_favorites table 🛡️ Authentication & Authorization: - All endpoints now require valid JWT tokens - Proper user isolation across all data operations - Collection permissions properly enforced - User-specific data queries implemented 🔧 Database Schema Fixes: - Card ownership now uses user_cards table - Favorites use user_favorites table - Decks filtered by user_id - Collections respect ownership and permissions ⚠️ Development Note: - Added warning for fallback authentication in dev mode - Should be removed in production deployment ✅ Data Privacy Secured: - Users can only see their own collections, decks, and owned cards - Public collections visible to all (as intended) - Shared collections respect permission levels - No cross-user data leakage		2025-07-26 00:29:51 -05:00
