I got an email that indicates I was developing in "test mode", but that it left my database completely open to the internet. The default rules I initially accepted look like this:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
// This rule allows anyone on the internet to view, edit, and delete
// all data in your Firestore database. It is useful for getting
// started, but it is configured to expire after 30 days because it
// leaves your app open to attackers. At that time, all client
// requests to your Firestore database will be denied.
//
// Make sure to write security rules for your app before that time, or else
// your app will lose access to your Firestore database
match /{document=**} {
allow read, write: if request.time < timestamp.date(2019, 12, 14);
}
}
}
What needs to be done to satisfy the request of this email?
The security rules shown here are a departure from the previous default rules that were much more permissive. The idea with this rule:
match /{document=**} {
allow read, write: if request.time < timestamp.date(2019, 12, 14);
}
Is that you get unrestricted access to your Firestore database up until the given date, in order to freely experiment with it for a month. However, allowing unrestricted access is obviously a massive security hole in the long run.
The recommended course of action is to first remove this rule entirely as it allows anyone to read and write anything in your database. Then, devise some proper rules that allow only access to collections and documents that your eventual users should be able to access. A full discussion of that is off-topic for Stack Overflow (as we don't know your app's requirements), but here are some good places to start learning about security rules:
The documentation
This video series
What you should be doing is calling out the access constraints for each collection and subcollection in your database. Ideally, you should lock down unauthenticated write access to all collections, except where absolutely required. In the best case, you're using Firebase Authentication to help control access to documents only as required for authenticated users.
Alternatively, if you're done working with the database (for the time being), you can block access to the database from web and mobile client entirely by using the following rule exclusively:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
allow read, write: if false;
}
}
With this rule, access from backend code using the Firebase Admin SDK or other Cloud SDKs will still be allowed.
Or if you are like me, who's still in test mode? Just update the date
match /{document=**} {
// from previous date 2019, 12, 14 to new date 2020, 01, 4
allow read, write: if request.time < timestamp.date(2020, 01, 4);
}
Whenever you start a new project on firebase (or) setup a firestore database, firebase by default adds a set of rules for your database, which looks something like this.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
// This rule allows anyone on the internet to view, edit, and delete
// all data in your Firestore database. It is useful for getting
// started, but it is configured to expire after 30 days because it
// leaves your app open to attackers. At that time, all client
// requests to your Firestore database will be denied.
//
// Make sure to write security rules for your app before that time, or else
// your app will lose access to your Firestore database
match /{document=**} {
allow read, write: if request.time < timestamp.date(XXXX, XX, XX);
}
}
}
The "timestamp.date" dates to 1 month from when you start the project. More or less like a 30day free trial.
Upon bypassing this date, the database denies all the client requests.
So, the email is basically a reminder for you to change the security rules.
One simple way is to allow read/write requests only to authenticated users.
// Allow read/write access on all documents to any user signed in to the application
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}
Note that, this is one of the ways to define the rules and need not exactly as shown, you could further make modifications as per your requirements.
For more information, you can have a look at this documentation
When you create a firestore db, you get access for 30 days. Your rule looks like this. See date, allowing read/write for certain duration,
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2021, 8, 17);
}
}
}
The date part is important here. You can increase this date if you want to use it in Test mode for longer period.
request.time < timestamp.date(2021, 10, 30);
OR, it's better to set access to any authenticated user while you're developing your app, like
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}
Its good to be more specific always, especially when you are deploying in production. In that case your rule can be,
match /some_collection/{userId}/{documents=**} {
allow read, write: if request.auth != null && request.auth.uid == userId
}
You can read more in detail in official documentation - https://firebase.google.com/docs/rules/basics
Firebase] Client access to your Cloud Firestore database expiring in 2 day(s)
You chose to start developing in Test Mode, which leaves your Cloud Firestore database completely open to the Internet. Because your app is vulnerable to attackers, your Firestore security rules were configured to stop allowing requests after the first 30 days.
In 2 day(s), all client requests to your Firestore database will be denied. Before that time, please write strong security rules that allow your app to function while appropriately protecting your data. Analysis is run daily; if you've modified your rules in the last 24 hours those changes may not be accounted for.
If u receive this kind of email from the firebase then you have to go to the edit rules and then change the date simply.
As you are using Firestore in Test Mode which provides a trail of 30 days.
After that if you want to use it for a longer duration, you need to update the rules in Firestore.
Your current rule would look like:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2022, 1, 18);
}
}
}
Now you need to update it !
Alternatively, You can increase this date if you want to use it in Test mode for longer period (it can be increased for 1 month from today).
OR, it's better to set access to any authenticated user while you're developing your app, like
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.auth != null;
}
}
}
OR If you are deploying in production. In that case your rule could be,
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.auth != null && request.auth.uid == userId;
}
}
}
Just change your rule by any of the above 2 rules and you are all good to go.
Alright so I was creating an application that works with firebase and when a user signs in, user's ID is stored in the data base. But when I was creating this I ran into an error that would pop up after a user signs in FirebaseError: Missing or insufficient permissions..
I did some research. It was the firestore rules, which were set to default as
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
}
}
I changed this as
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
That's right from false to true. Is the right way to do it? Help would be appreciated.
If you are just testing and no one is going to use it it's fine but please, keep in mind that this kind of ruleset allows everyone to read and write to each of your files under the documents collection.
I ran into this kind of problem too while starting out with firebase and I know it's overwhelming but I would suggest you try and implement a ruleset more secure following this get started guide by google.
Let me know if you need any further information.
I want unlogged users of my reactjs webapp to be able to read only "business profile collection".
I have the following db structure.
And the following rules:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read : if true;
allow write: if request.auth != null;
}
}
}
I am quite new to the firestore rules, i have multiple ways and this is the only one that worked for me.
The user Dharmaraj previously mentioned that your rules are allowing any user to read and write to any collection of the database, something you can validate using the rules playground. If that is the desired behavior, then you can ignore these alerts.
However, you said you wanted unlogged users of your app to be able to read only “business profile collections”. You can read the Production-ready rules and its sections, then use the one that is best for you. The way I see it, you should read and use the Attribute-based and Role-based access section and finish with something like this:
service cloud.firestore {
match /databases/{database}/documents {
// For attribute-based access control, Check a boolean `admin` attribute
allow write: if get(/databases/$(database)/documents/users/$(request.auth.uid)).data.admin == true;
allow read: true;
// Alternatively, for role-based access, assign specific roles to users
match /some_collection/{document} {
allow read: if get(/databases/$(database)/documents/users/$(request.auth.uid)).data.role == "Reader"
allow write: if get(/databases/$(database)/documents/users/$(request.auth.uid)).data.role == "Writer"
}
}
}
Although, you might want to check them and read them carefully to see if any other option is more suitable for you. I will add the Security Rules language that is needed to understand what your rules are doing and how to Fix insecure rules.
I am just starting in firebase with databases and I have a problem, I am making a page about an online store where I do not want there to be any kind of authentication, I just want the products to be seen with a brief description, but the problem is that every day a firebase email arrives telling me that my rules are insecure, so I wanted to know how to set my rules so that they are safe and only the information is displayed on my own page.
These are the rules I currently use:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow write: if false; allow read: if true;
}
}
}
I understand that they are open to all people, my idea is that at the moment it does not save any type of sensitive information in my database, I just want to save product data about my store, such as the price or a description avoiding all sensitive information. , my object is to return the safe rules and to be able to see the data from my page without any type of authentication for it.
I'll wager that google would consider the rules sufficiently locked down if the specific collection path was spelled out....
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /Put_Your_Product_Collection_Path_Here/{productDoc=**} {
allow write: if false; allow read: if true;
}
}
}
If you have other collections, be sure to secure those, too.
I've appended the following line to my storage rules following the docs:
rules_version = '2';
Furthermore, my rules are now:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
Moreover, I am able to list out the files of a folder using listAll which is an exclusively version 2 feature.
However, each day I come back to my dashboard to find my rules updated to the previous version, being:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
How and why does this happen? More importantly, how may I fix the issue?
With the help from Jonathan from Firebase who was kind enough to remind me of the fact that I am deploying almost on a daily basis I figured out what was going wrong. It turned out that as part of my continuous deployment I was also deploying Firebase storage rules, hence I was indirectly the one overriding my own rules.
Now the obvious and easy solution is to just update the storage.rules file locally.
There are only three ways your rules can change:
Using the Firebase console
Using the Firebase CLI to deploy rules from a local file
Use the Firebase Admin SDK.
If your rules are changing and you are absolutely certain that it's not coming from one of these two methods, contact Firebase support for assistance.
