ASP.NET Core 6: implementing Role-Based Authorization optimization guide for Lazy Loaded Data
I'm wondering if anyone has experience with This might be a silly question, but Quick question that's been bugging me - I'm working with an scenario where my role-based authorization is not functioning correctly for data that is lazy loaded in my ASP.NET Core 6 application... I'm using Entity Framework Core to fetch user roles and associated data, but it seems that the authorization policies aren't being applied until after the data has been loaded, leading to unauthorized access errors. Here's a simplified version of my controller code: ```csharp public class MyController : Controller { private readonly IMyService _myService; public MyController(IMyService myService) { _myService = myService; } [Authorize(Roles = "Admin")] public async Task<IActionResult> GetAdminData() { var data = await _myService.GetDataAsync(); return Ok(data); } } ``` In my service, I'm using lazy loading to get user-related data: ```csharp public class MyService : IMyService { private readonly MyDbContext _context; public MyService(MyDbContext context) { _context = context; } public async Task<List<Data>> GetDataAsync() { return await _context.Users.Include(u => u.UserRoles).ToListAsync(); } } ``` When a non-admin user accesses the `GetAdminData` endpoint, I expect it to return a `403 Forbidden`, but instead, it's returning the data without any restrictions. I have confirmed that the `User` object contains the correct roles after loading the data, but the authorization seems to be bypassed for lazy-loaded properties. I've tried using `[Authorize(Policy = "RequireAdminRole")]` with a custom policy, but the scenario continues. Additionally, I've checked the `Startup.cs` configuration: ```csharp services.AddAuthorization(options => { options.AddPolicy("RequireAdminRole", policy => policy.RequireRole("Admin")); }); ``` Could this scenario stem from how lazy loading interacts with the authorization framework? Is there a recommended way to handle role checks with lazy-loaded data in ASP.NET Core? Any insights would be greatly appreciated. Any ideas what could be causing this? How would you solve this?
