From e90a907e9e730961acb14bee912949d45a835bcf Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Wed, 26 Nov 2025 22:16:30 -0600 Subject: [PATCH] CLAUDE: Implement server-side OAuth flow with HttpOnly cookies MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes iPad Safari authentication issue where async JavaScript is blocked on OAuth callback pages after cross-origin redirects (Cloudflare + Safari ITP). **Problem**: iPad Safari blocks all async operations (Promises, setTimeout, onMounted) on the OAuth callback page, preventing frontend token exchange. **Solution**: Move entire OAuth flow to backend with HttpOnly cookies, eliminating JavaScript dependency on callback page. ## Backend Changes (7 files) ### New Files - app/services/oauth_state.py - Redis-based OAuth state management * CSRF protection with one-time use tokens (10min TTL) * Replaces frontend sessionStorage state validation - app/utils/cookies.py - HttpOnly cookie utilities * Access token: 1 hour, Path=/api * Refresh token: 7 days, Path=/api/auth * Security: HttpOnly, Secure (prod), SameSite=Lax ### Modified Files - app/api/routes/auth.py * NEW: GET /discord/login - Initiate OAuth with state creation * NEW: GET /discord/callback/server - Server-side callback handler * NEW: POST /logout - Clear auth cookies * UPDATED: GET /me - Cookie + header support (backwards compatible) * UPDATED: POST /refresh - Cookie + body support (backwards compatible) * FIXED: exchange_code_for_token() accepts redirect_uri parameter - app/config.py * Added discord_server_redirect_uri config * Added frontend_url config for post-auth redirects - app/websocket/handlers.py * Updated connect handler to parse cookies from environ * Falls back to auth object for backwards compatibility - .env.example * Added DISCORD_SERVER_REDIRECT_URI example * Added FRONTEND_URL example ## Frontend Changes (10 files) ### Core Auth Changes - store/auth.ts - Complete rewrite for cookie-based auth * Removed: token, refreshToken, tokenExpiresAt state (HttpOnly) * Added: checkAuth() - calls /api/auth/me with credentials * Updated: loginWithDiscord() - redirects to backend endpoint * Updated: logout() - calls backend logout endpoint * All $fetch calls use credentials: 'include' - pages/auth/callback.vue - Simplified to error handler * No JavaScript token exchange needed * Displays errors from query params * Verifies auth with checkAuth() on success - plugins/auth.client.ts * Changed from localStorage init to checkAuth() call * Async plugin to ensure auth state before navigation - middleware/auth.ts - Simplified * Removed token validity checks (HttpOnly cookies) * Simple isAuthenticated check ### Cleanup Changes - composables/useWebSocket.ts * Added withCredentials: true * Removed auth object with token * Updated canConnect to use isAuthenticated only - layouts/default.vue, layouts/game.vue, pages/index.vue, pages/games/[id].vue * Removed initializeAuth() calls (handled by plugin) ## Documentation - OAUTH_IPAD_ISSUE.md - Problem analysis and investigation notes - OAUTH_SERVER_SIDE_IMPLEMENTATION.md - Complete implementation guide * Security improvements summary * Discord Developer Portal setup instructions * Testing checklist * OAuth flow diagram ## Security Improvements - Tokens stored in HttpOnly cookies (XSS-safe) - OAuth state in Redis with one-time use (CSRF-safe) - Follows OAuth 2.0 Security Best Current Practice - Backwards compatible with Authorization header auth ## Testing - ✅ Backend OAuth endpoints functional - ✅ Token exchange with correct redirect_uri - ✅ Cookie-based auth working - ✅ WebSocket connection with cookies - ✅ Desktop browser flow verified - ⏳ iPad Safari testing pending Discord redirect URI config ## Next Steps 1. Add Discord redirect URI in Developer Portal: https://gameplay-demo.manticorum.com/api/auth/discord/callback/server 2. Test complete flow on iPad Safari 3.
