I have built an mobile app & web app for my firebase storage/bucket to view my storage data. The security rules I have kept are read and write for all users but after some days it gets back to the default security rules. My storage is also in "production mode". Can anyone guide me on why it keeps happening?
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}

I have initially used this below, everything was working fine.
some days after I received an email for google saying my data can be seen by anybody.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
after some searchs, i found this :
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: request.auth != null;
}
}
}
Just after modifying those rules, I have my own backend for authentification :
Error i keep receiving :
Exception has occurred.
FirebaseException ([cloud_firestore/permission-denied] The caller does not have permission to execute the specified operation.)
As Jared commented, Firebase has no way to know that the user signed in to your backend, unless you tell it about it. This is known as custom authentication in Firebase, or building a custom provider for Firebase Authentication.
The process consists of:
Gathering the user's credentials and signing them in on your system.
In a trusted environment then minting a Firebase Authentication token for that user, and passing that back to the client.
Signing in to Firebase with the custom token (also see this page).
I stored my portfolio app data using Firestore and firebase storage.
There are no user inputs or registration in my app, it's a simple portfolio to show my works.
I want any user to be able to read the data coming from my firestore and firebase storage.
My current rules:
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read: if true;
}
}
}
The problem i have with this rules is that attackers can fluid my app with requests.
I even got warning email says
"Because your project does not have strong security rules, anyone can access your entire database. Attackers can read all of your data, and they can drive up your bill."
I do not have any sensitive data stored but i want to prevent additional charges from google.
How can i set my Firestore security rules to enable any users to read without auth but prevent attacks?
Firebase Security Rules don't like when a database point is left open, while this is normally done with Security Rules and Auth, You can define the readability of the document based on a value from inside the document.
In this example, the document has a bool value for Public
service cloud.firestore {
match /databases/{database}/documents {
// Allow the user to read data if the document has the 'visibility'
// field set to 'public'
match /{document=**} {
allow read: if resource.data.public == true;
}
}
}
I have received an email from Firebase stating the title of this post with these details:
We've detected the following issue(s) with your security rules:
any user can read your entire database
any user can write to your entire database
My Firebase database rules are as follows:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
I am not sure what to do. For my app users need to be able to read mostly and write (sometimes to submit stuff). Does anyone have tips to secure this better, or even if I can do anything?
Do you use Firebase Authentication in your app? If yes, then change the security rules to this :
allow read, write: if request.auth != null;
This rule will allow only logged-in user to get and write data to database. This should be a good starting point for a simple app. However, if you are not using Firebase Authentication, then you must implement your own authenticate scheme, but this is just not recommended for security
Firstly:
I am using currently Firebase only for analytics (users count) and crashes for mobile app. No usage of Firebase Storage, Realtime Database or Firestore (none of those were configured or set up).
Question:
Do I still need to define some security rules in the Firebase?
When you create a Firebase project, neither of the databases nor a storage bucket are auto-created. So at that point there is no risk of them being abused by malicious users.
If you create a database or storage bucket through the console, it will ask what security rules to apply. If you select the restrictive rules there (the ones that have false in them, the database or bucket will be inaccessible, so there's also no risk of abuse.
If you (accidentally) pick the more permissive rules though, users can access your database or bucket, even when your application does not. In that case, you'll want to set the most restrictive rules:
Realtime Database
{
"rules": {
".read": false,
".write": false
}
}
source
Firestore
// Deny read/write access to all users under any conditions
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
}
}
source
Storage
// Access to files through Firebase Storage is completely disallowed.
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if false;
}
}
}

I am trying set up Firebase security rules for Cloud Firestore that only i can write. But Everyone can be read it.
Here is my rules:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /users/{user} {
allow read, write: if request.auth.uid != null;
}
}
}
I am not sure set up the security rules for it. How do i set up or test with simulator that user information view able only by the user and admin?
There are two ways to test your rules. You can use the rules simulator in the Firebase console. Go to the rules tab to find it.
You can also test rules locally using the Firestore rules emulator, using code to check if the rules do what you expect.
