+ Object.entries(params).forEach(([key, value]) => { + query = query.replace(`{{${key}}}`, String(value)); + }); + return query; +} +``` + +**Attack Example**: +```typescript +const tableName = "users;

+ } +} +``` + +**Security Improvements**: +- ✅ Regex validation for identifiers: `^[a-zA-Z_][a-zA-Z0-9_]{0,62}$` +- ✅ Enum validation against whitelist +- ✅ Drizzle ORM patterns using `sql.identifier()` +- ✅ Parameterized queries with `$1, $2` placeholders +- ✅ No string interpolation or concatenation +- ✅ Type-safe validation before query execution + +**Usage Example**: +```typescript +// Validate parameters +const validation = validateSqlTemplateParams('tables', 'dropTable', { + tableName: 'users' +}); + +if (!validation.valid) { + throw new Error(`Invalid parameters: ${validation.errors.join(', ')}`); +} + +// Use sanitized values with Drizzle +const { tableName } = validation.sanitized; +await db.execute(sql`DROP TABLE ${sql.identifier([tableName])}`); +``` + +**Blocks**: +```typescript +// ❌ These will be rejected by validation +validateSqlParameter('tableName', 'users; DROP TABLE users--'); +// Returns: { valid: false, error: 'Invalid identifier format' } + +validateSqlParameter('dataType', 'MALICIOUS'); +// Returns: { valid: false, error: 'Invalid enum value' } +``` + +--- + +### 3. ✅ Type Safety Issues (MEDIUM) + +**Location**: `src/utils/featureConfig.ts` + +**Previous Implementation**: +```typescript +export function getStorybookStory(componentName: string, storyName: string): any { + return config.storybookStories?.[componentName]?.[storyName]; +} + +export function getAllStorybookStories(): Record { + return config.storybookStories || {}; +} +``` + +**New Implementation**: +```typescript +export function getStorybookStory( + componentName: string, + storyName: string +): StorybookStory | undefined { + return config.storybookStories?.[componentName]?.[storyName]; +} + +export function getAllStorybookStories(): Record> { + return config.storybookStories || {}; +} +``` + +**Security Improvements**: +- ✅ Proper TypeScript types throughout +- ✅ No `any` types in public APIs +- ✅ Better IDE autocomplete and type checking +- ✅ Compile-time error detection + +--- + +## Test Results + +All unit tests pass: +``` +✓ unit src/validations/DatabaseIdentifierValidation.test.ts (12 tests) +✓ unit src/utils/featureConfig.test.ts (134 tests) +✓ unit src/utils/Helpers.test.ts (2 tests) + +Test Files 3 passed +Tests 148 passed +``` + +--- + +## Security Architecture + +### Component Tree Templates + +**Threat Model**: +- Malicious template expressions in features.json +- Arbitrary JavaScript execution via `new Function()` +- File system access, network requests, process termination + +**Mitigation**: +1. **Safe Property Access**: Only dot-notation paths allowed +2. **Regex Validation**: Path must match `^[a-zA-Z_$][a-zA-Z0-9_$.]*$` +3. **Whitelisted Operators**: Limited to comparison and logical operators +4. **Whitelisted Math**: Only safe Math operations allowed +5. **No Function Calls**: Blocks `require()`, `eval()`, etc. + +### SQL Templates + +**Threat Model**: +- SQL injection via table/column names +- Unauthorized data access or modification +- Database schema manipulation + +**Mitigation**: +1. **Parameter Validation**: All identifiers validated with regex +2. **Enum Whitelisting**: Data types, index types validated against allowed list +3. **Drizzle ORM**: Uses `sql.identifier()` for automatic escaping +4. **Parameterized Queries**: Uses `$1, $2` placeholders +5. **No String Interpolation**: No template string replacement +6. **Type Checking**: TypeScript types enforce correct usage + +--- + +## Recommendations + +### For Developers + +1. **Always validate parameters** before using SQL templates: + ```typescript + const validation = validateSqlTemplateParams(category, template, params); + if (!validation.valid) throw new Error(validation.errors.join(', ')); + ``` + +2. **Use Drizzle ORM methods** over raw SQL when possible: + ```typescript + // Preferred + await db.insert(table).values(data); + + // If raw SQL needed + await db.execute(sql`SELECT * FROM ${sql.identifier([tableName])}`); + ``` + +3. **Never bypass validation** - always use the provided helper functions + +### For Reviewers + +1. Look for any usage of `new Function()`, `eval()`, or string interpolation +2. Verify all SQL queries use parameterized queries or `sql.identifier()` +3. Check that parameter validation is performed before query execution +4.
