[BUG] Missing Query Validation and Security #76
Description
Basic write query detection exists, but comprehensive query validation and security measures are missing.
Missing Components:
- SQL injection protection
- Query complexity analysis
- Resource usage limits
- Query sanitization
- Dangerous operation detection
Expected Implementation:
// app/lib/sql/validator.ts
class QueryValidator {
validateQuery(query: string, userPermissions: Permission[]): ValidationResult {
// Check for SQL injection patterns
// Validate query complexity
// Check resource usage limits
// Verify user permissions
}
sanitizeQuery(query: string): string {
// Remove dangerous operations
// Limit query scope
}
}Acceptance Criteria:
- SQL injection protection
- Query complexity limits
- Resource usage monitoring
- Dangerous operation detection
- Permission-based query restrictions
