Flutter - [Firebase] Your Cloud Firestore database has insecure rules - firebase

I Don't know why I am getting this mail, I never used Firebase Database in my flutter project,
After clicking on the hyperlink it redirects to this code
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}

If you do not intend to to use Cloud Firestore Database at all in your project, I'd suggest turning off all read/writes. That will also stop the email-reminders of the insecure rules.
Simply change the allow read, write: if true; to allow read, write: if false;
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
}
}

Still receiving email in Firebase about database expiring despite updating the Firestore Rules

I am fairly new to Firebase Firestore, and this email states that my database will expire. I modified my rules one day ago, however, I still receive this email.
Here is the email sent to me:
Over here are the rules I updated for Firestore:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /dishes/{dish} {
allow write: if request.auth != null;
allow read: if true;
}
}
}
And over here are the test mode rules (before the update):
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2023, 1, 27);
}
}
}
I don't understand, I have already updated my Firestore Rules, but I still receive that my database will expire soon. Any help would be great!
PS:
I am still new to Firebase/Firestore

Firestore permission error in test database mode

I know that questions about Firestore permission errors have been asked a lot, but my situation may be unique. This is because of three things:
my database is in test mode which should allow access to anyone (right?)
I am getting the error while simulating my app with an authenticated firebase user
I am able to write data--the error only happened while reading it.
Here are my security rules:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2021, 12, 31);
}
}
}
Here is a screenshot of a description of Firestore's test database mode:
The actual error I got was this:
Error: Error Domain=FIRStorageErrorDomain Code=-13021 "User does not have permission
to access gs://zimmerfour.appspot.com/senderID." UserInfo={object=senderID,
ResponseBody={
"error": {
"code": 403,
"message": "Permission denied. Please enable Firebase Storage for your bucket by visiting the Storage tab in the Firebase Console and ensure that you have sufficient permission to properly provision resources."
EDIT:
I haven't changed the overall Cloud Storage rules. They are still set to the default of:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
The error message is coming from Cloud Storage for Firebase (as indicated by FIRStorageErrorDomain and the error message), which is protected by its own set of security rules in your project.
Try this method, it worked for me :)
// if you want to allow for all to read, write
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write;
}
}
}
// if you want to allow for all to read, and authenticated users to write
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read;
allow write: if request.auth != null;
}
}
}
// if you want to allow for only authenticated users to write or read
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}

Firebase Flutter : Cloud Firestore database has insecure rules

Firebase keep telling me
We've detected the following issue(s) with your security rules:
any user can read your entire database
I have changed the rules but that rules doesn’t work in my app because all user can read from db and only authenticate user can write to db.
Firebase says that write and read should be performed until we login. But in my case every user can read and only login user can write.
Any ideas how to solve this ? or I'm I doing it wrong ?
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read;
allow write: if request.auth != null;
}
}
}
Can you set your read to false explicitly?
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read: if false;
allow write: if request.auth != null;
}
}
}
That should do it. Let me know if it persists.
The root cause is that even though you are allowing only authenticated users to read or write but they have access to the whole database as mentioned in the Google Cloud Firestore Documentation. That also means any authenticated user can write anything in your database.
If you database has a separate document for each user, I would suggest using the following rules which allows users to write/read their own data only.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /users/{userId} {
allow read, write: if request.auth.uid === userId;
}
}
}

Firebase rules change

I want to stop reading data from firebase by using rules change. Here is the rules:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write;
}
}
}
I want to disallow all. How to do that ?
Change this:
allow read, write;
to this:
allow read, write: if false;

flutter app is unable to ineract with firebase cloud database

i have set my firebase cloud database rule to default
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
}
}
but while my flutter app tries to interact with it, this error occurs
Error performing get, PERMISSION_DENIED: Missing or insufficient permissions., null
This condition:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
}
}
means you are disallowing both read and write from and to firestore, you can change the rules to the following:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read : if true;
allow write: if false;
}
}
}
Which will allow you to read but not write to the database, or you can use the following:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.time < timestamp.date(2020, 9, 20);
}
}
}
Use the above rules just for testing, check here:
