Razorpay Payment System Fix
Resolved critical payment processing failure causing "Internal server error" on all plan purchases. Root cause: Google OAuth users had no corresponding database record, triggering a foreign key constraint violation when creating payment orders.
Google OAuth User Provisioning: Added signIn callback to NextAuth that ensures a User row is created in the database on first Google sign-in, resolving the foreign key violation that blocked payment order creation
PlanTier Enum Correction: Fixed wallet authentication user creation setting plan to lowercase "free" instead of "FREE", which violated the PlanTier enum constraint on new wallet signups
Razorpay Credential Sanitization: Added .trim() to all Razorpay environment variable getters (key ID, key secret, webhook secret) to prevent authentication failures caused by trailing whitespace in .env values
Environment Variable Cleanup: Removed trailing whitespace from RAZORPAY_KEY_SECRET in the .env file that could cause Razorpay API signature mismatches
Payment Error Responses: Replaced generic "Internal server error" with actionable error messages that distinguish between missing user accounts, misconfigured payment services, and transient failures
P0 Critical Security & Core Functionality Fixes
Resolved all 7 critical/broken functionality issues identified in the full-project audit. These fixes address authentication bypasses, broken encryption, and non-functional core features.
File Download Decryption: Replaced empty-buffer placeholder with full AES-256-GCM decryption pipeline, downloads IPFS ciphertext, reconstructs encryption params from DB, derives key via PBKDF2, and returns the decrypted file
IPFS Encryption Enforced: Fixed addFileToVault() uploading plaintext to IPFS, now serializes and uploads the encrypted data buffer instead of the original file
Vault ID Extraction: Replaced hardcoded vaultId: 0 with waitForTransactionReceipt + decodeEventLog to parse VaultCreated event and extract the real on-chain vault ID
Deploy Script Corrected: Replaced all NilVault references with TALAVault, updating artifact path, contract variable names, environment contract address entry, and deployment logs
Login Signature Verification: Rewrote /api/auth/login to require EIP-191 wallet signature, verifies message plus nonce cryptographically via viem before issuing JWT (prevents impersonation)
Admin Auth Hardened: Replaced base64 mock token with proper JWT (HS256, 4h expiry, admin role claim), added crypto.timingSafeEqual for credential comparison, and per-IP brute-force lockout (5 attempts → 15min)
Real Vault Creation Enabled: Removed disabled={!demoMode} gate from submit button, non-demo vault creation now fully functional with "Create Time-Locked Vault" CTA
P1 Security Vulnerability Fixes
Resolved all 7 security vulnerability issues from the full-project audit. Hardens authentication, secrets management, CSRF protection, input sanitization, and rate limiting across the application.
JWT Secret Enforcement: Removed hardcoded fallback secret, application now throws a fatal error at startup if JWT_SECRET env var is missing or shorter than 32 characters
Share Link Hardening: Removed keyHash from the share endpoint Prisma query and API response, vault password hashes are no longer exposed through share links
Pinata Secrets Secured: Renamed NEXT_PUBLIC_PINATA_API_KEY and NEXT_PUBLIC_PINATA_SECRET_API_KEY to server-only env vars (PINATA_API_KEY, PINATA_SECRET_API_KEY) preventing browser exposure
Wallet Auth Implemented: NextAuth Credentials provider authorize() now performs full EIP-191 signature verification via viem with Prisma user find-or-create, replacing the previous null return
CSRF Protection Enforced: CSRF tokens now generated with crypto.getRandomValues, set as cookies on all responses, and validated on all state-changing requests across all environments with exemptions for auth endpoints
Input Sanitization Applied: secureApiHandler now attaches sanitized request body to context.sanitizedBody so handlers can access it after the request stream is consumed
Auth Rate Limiting: Applied rateLimit() middleware with auth config (10 req/min per IP) to /api/auth/login, /api/auth/wallet, and /api/admin/login endpoints
