[5.0] route model binding runing before middleware #6118
Comments
Pull request to fix? |
@GrahamCampbell, i have no idea that how is it gonna be resolved. |
@taylorotwell this is critical bug. please fix it. |
@alioygur This is NOT critical. Any bug that affects laravel 5 is low priority. DO NOT USE LARAVEL 5 IN PRODUCTION |
Why would this be a bug? |
@taylorotwell, I thinking this is bug. Because, Imagine you use http basic authentication. (Stateless) So, user authenticated at middleware (AuthenticatedWithBasic) And you have a route and model binding, like this // routes.php
// routeserviceprovider@before
So, I maybe do somethings with current logged in user order model binding. Currently I can not this because model binding running before middlewares. I am sorry, for my bad English . |
I still don't understand. On Tuesday, October 21, 2014, ali oygur notifications@github.com wrote:

okey, just one question SO, what I supposed to do if I try to get the current logged in user information while binding model.
I am getting following error.

|
So basically, in order to find out if the bound object belongs to the authenticated user, you will need access to the current user in the bind callback. |
@JoostK yep! you are right. |
I'm in the same boat as @alioygur. Any possible solution to this issue yet? Otherwise, I'm afraid I would have to get rid of all my route model bindings sadly :( |
This shouldn't have been closed, delaying model binding until after the session data is available makes kind of sense. |
I came across the same issue. Imagine you have a admin panel where you can manage the users that can login into your website. As admin you want to be able to see users by browsing to |

This is my (resource) controller constructor:
This is my guest middleware:
And in routes.php:
I have tried the beforeFilter in the constructor and a group filter in routes.php but both still gave a 404 not found, browsing as guest. |
Just to chime in, I was roughly trying to do something like the following, but it fails due to this issue: Route model (or repository in my case) bindings in public function register()
{
$repoAbstract = 'App\Contracts\Repositories\Order';
$router->bind('order', function ($value) use ($repoAbstract) {
$repo = App::make($repoAbstract);
if ($model = $repo->find($value)) {
return $repo;
}
throw new NotFoundHttpException('Repository ' . $repoAbstract . ' could not find the model!');
});
} And this is Order repository's public function find($id)
{
$model = $this->model
->where('id', $id)
->where('user_id', Auth::id())
->first();
if ($model) {
$this->setModel($model);
}
return $model;
} The However, using route model (or repository in my case) bindings will fail for the above scenario, since the user hasn't yet been authenticated, which will cause the repository's As it stands right now, although I think route model bindings are pretty cool, I've had to disable all of them sadly, since they won't work for my scenario which is quite common frankly. |
I just ran into a similar issue, but it was pretty easy to get around with dependency injection:

This is not a bug, but a feature. I was talking to Taylor about this earlier today, not in relation to this though. |

There is an easy fix for those who are stuck with this issue. Instead of using the bind method in the service provider, just replace the route parameter with the object using middleware.
Cheers ;) |
Thanks @LPMadness good example! |
Doing your own route binding from a middleware isn't that bad tbh. Infact, I quite like that idea, and might even write one and publish it as a package. :) |
Maybe this is not the smartest way but I just wrapped my bindings in the
EDIT: DOES NOT WORK. Oh gosh, does not work because Auth::check() will always return false at this stage. |
I think i have the same problem. Using model binding makes my global scope fail as i need to get in this scope authenticated user ID but it is always NULL in that case. So Laravel throws |
+1 for this fix. Auth should come before the route model binding. In my case I'm using JWT for auth, so definitely need the auth check first before route check... In my case the api exposes certain parameters from a model based on privilege levels. So for instance a users profile only exposes an |
+1 since route binding comes first, the authenticated user doesn't exist in my I feel like this is a pretty core use case -- @taylorotwell can you comment on why this issue was closed? EDIT: Just read this: #6118 (comment) however perhaps there ought to be some consideration into how this was implemented in the first place given that so many people encounter this use case. It'd be great to see this functionality as part of the core route model binding feature, however it gets implemented.

Another month gone by, anyone attempted to fix this show stopper? |
Laravel is Taylor's personnel project not an open source protect.

This problem just bit me. I just learned that a user/attacker of my app was hitting an endpoint to see if records existed. Basically he was phishing the database. It wasn't really a DDOS attack because he was phishing each record manually so each request looked like normal. Long story short, once he learned which records did not exist he took that info to somebody else to complain about their work. I learned of this phishing from that third person that was concerned about how the attacker new which records were deleted. I'll spare you the details of why those records were deleted because the real issue seems to me that an UNAUTHENTICATED user was able to phish my database. THAT IS A SECURITY VULNERABILITY. What is the actual reason that authentication does/can not happen before route model binding? |
@devinfd I think this issue has been resolved by now. Can't reproduce the behaviour you're talking about. You could try creating a new project and see if it still has this behaviour. If you find out it doesn't, it's probably in the configuration of your project. If you believe you discovered a security vulnerability, you also shouldn't discuss it on Github, but email Taylor instead: https://laravel.com/docs/5.5/contributions#security-vulnerabilities |
@GuidoHendrik Thanks. My app is 5.5 and the bug does exists however I tried it on a fresh install of 5.5 and the bug did not exists. Long story short I discovered that the my app was using the old auth middleware |
@JosephSilber @taylorotwell I completely disagree that this use case should just be ignored - it's one of my real niggles with the framework at the moment; middlewares are fired after route model binding. This means that if you have a multi tenant application, or language-driven application, or global scopes, etc then your out of luck using the default built in route model binding: $router->bind('account', function($id) {
return Account::where('tenant_id', session('tenant_id'))->findOrFail();
}); Broke. I can understand why the middlewares are fired after route model binding, but I don't believe it's outside the scope of the application to at least provide functionality to bind AFTER middlewares have fired. Something like: Route::bindAfterMiddleware(function() {
Route::bind('product', function($slug) {
return Product::where('lang', session('lang_code', 'us'))->where('slug', $slug)->firstOrFail();
});
}); Or for implicit route binding, hint which parameters should be bound after middlewares: Route::bindAfterMiddleware('product'); Or for binding after session middleware only: Route::bindAfterMiddleware('product', 'Illuminate\Session\Middleware\StartSession'); Something like that. There really ought to be a way to cater for this without resorting to creating your own middleware to replace parameters in the url etc, otherwise it renders the whole route model binding feature quite useless in those cases. This would also help with any DDoS driven attacks based on urls as you could tell it to bind routes models AFTER throttler has run, etc. Ref my suggestion: laravel/ideas/issues/508 |
Loading in the models via binding before checking auth in middleware reminds me of Spectre! |
Yah, it's definitely not ideal and I can totally understand the DDoS argument. Even if the throtter in Laravel would deny the request, your models have still already loaded and your more susceptible to a DDoS driven style attack on the database. Like you said though, I wouldn't use that as an argument to fix this, though a fix would likely help with the DDoS issue too. |

I rarely use(d) route binding, but for a new project I'm using https://github.com/Propaganistas/Laravel-FakeId which auto-resolves models from their fake ID and that kind of requires route binding. Of course, that's when I ran into this issue. Wanted to apply global scopes to those models before they were resolved, but Laravel does it the other way around. I can understand from a certain point of view, you want consistency. But sometimes that's a no-go security and usability-wise. Here's my attempt at fixing the issue: https://gist.github.com/sebastiaanluca/d61e9e2bc874615f82cfd679dee8edce#gistcomment-2358542 Not a 100% covered and tested with this, but feedback welcome! |
Good news come with laravel 5.3 above
So now, the Route Model Binding is handled by Illuminate\Routing\Middleware\SubstituteBindings in web middleware group. Since the web middleware group always runs first, you can comment/remove this middleware in web middleware group and add it to routeMiddleware
after doing that, you can add the 'bindings' middleware in specific order in your route. e.g
in that example, 'auth' middleware run first before 'bindings' middleware. but, in below example, 'bindings' middleware run first before 'auth' middleware :
Hope it helps 👍 |
Adding a small tip to denifelixe's solution for this issue , I have a Route Group for Auth, Then Account Scopes (which sets scope for all models for the specific account type ie: only access owned resources, a custom middleware) , Then bindings : This is nice because the vast majority of my routes are within this group, And you can just add another group with just binding middleware bindings surrounding all other public routes as well. If you have an existing and complex routes structure (where this isn't necessarily easy to refactor or possible), Try adding the middleware Construct Method of every controller, which did solve this issue for me as well. :
