From b92d09e00623df0e5edb5de5e1453bfd5602c7ff Mon Sep 17 00:00:00 2001 From: Lawrence Liu Date: Sun, 9 Nov 2025 09:42:47 +0800 Subject: [PATCH] fix(database): prevent empty values from overwriting exchange private keys (#785) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(database): prevent empty values from overwriting exchange private keys Fixes #781 ## Problem - Empty values were overwriting existing private keys during exchange config updates - INSERT operations were storing plaintext instead of encrypted values - Caused data loss when users edited exchange configurations via web UI ## Solution 1. **Dynamic UPDATE**: Only update sensitive fields (api_key, secret_key, aster_private_key) when non-empty 2. **Encrypted INSERT**: Use encrypted values for all sensitive fields during INSERT 3. **Comprehensive tests**: Added 9 unit tests with 90.2% coverage ## Changes - config/database.go (UpdateExchange): Refactored to use dynamic SQL building - config/database_test.go (new): Added comprehensive test suite ## Test Results ✅ All 9 tests pass ✅ Coverage: 90.2% of UpdateExchange function (100% of normal paths) ✅ Verified empty values no longer overwrite existing keys ✅ Verified INSERT uses encrypted storage ## Impact - 🔒 Protects user's exchange API keys and private keys from accidental deletion - 🔒 Ensures all sensitive data is encrypted at rest - ✅ Backward compatible: non-empty updates work as before * revert: remove incorrect INSERT encryption fix - out of scope --- config/database.go | 52 +++- config/database_test.go | 589 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 631 insertions(+), 10 deletions(-) create mode 100644 config/database_test.go diff --git a/config/database.go b/config/database.go index c96d4251..e2531945 100644 --- a/config/database.go +++ b/config/database.go @@ -754,20 +754,52 @@ func (d *Database) GetExchanges(userID string) ([]*ExchangeConfig, error) { } // UpdateExchange 更新交易所配置，如果不存在则创建用户特定配置 +// 🔒 安全特性：空值不会覆盖现有的敏感字段（api_key, secret_key, aster_private_key） func (d *Database) UpdateExchange(userID, id string, enabled bool, apiKey, secretKey string, testnet bool, hyperliquidWalletAddr, asterUser, asterSigner, asterPrivateKey string) error { log.Printf("🔧 UpdateExchange: userID=%s, id=%s, enabled=%v", userID, id, enabled) - // 加密敏感字段 - encryptedAPIKey := d.encryptSensitiveData(apiKey) - encryptedSecretKey := d.encryptSensitiveData(secretKey) - encryptedAsterPrivateKey := d.encryptSensitiveData(asterPrivateKey) + // 构建动态 UPDATE SET 子句 + // 基础字段：总是更新 + setClauses := []string{ + "enabled = ?", + "testnet = ?", + "hyperliquid_wallet_addr = ?", + "aster_user = ?", + "aster_signer = ?", + "updated_at = datetime('now')", + } + args := []interface{}{enabled, testnet, hyperliquidWalletAddr, asterUser, asterSigner} - // 首先尝试更新现有的用户配置 - result, err := d.db.Exec(` - UPDATE exchanges SET enabled = ?, api_key = ?, secret_key = ?, testnet = ?, - hyperliquid_wallet_addr = ?, aster_user = ?, aster_signer = ?, aster_private_key = ?, updated_at = datetime('now') + // 🔒 敏感字段：只在非空时更新（保护现有数据） + if apiKey != "" { + encryptedAPIKey := d.encryptSensitiveData(apiKey) + setClauses = append(setClauses, "api_key = ?") + args = append(args, encryptedAPIKey) + } + + if secretKey != "" { + encryptedSecretKey := d.encryptSensitiveData(secretKey) + setClauses = append(setClauses, "secret_key = ?") + args = append(args, encryptedSecretKey) + } + + if asterPrivateKey != "" { + encryptedAsterPrivateKey := d.encryptSensitiveData(asterPrivateKey) + setClauses = append(setClauses, "aster_private_key = ?") + args = append(args, encryptedAsterPrivateKey) + } + + // WHERE 条件 + args = append(args, id, userID) + + // 构建完整的 UPDATE 语句 + query := fmt.Sprintf(` + UPDATE exchanges SET %s WHERE id = ?
