I am new in firebase, so the question that i want to ask is how to set firebase security rules as public. Anyone know the code?
Here is the security rules of my firebase now:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read;
allow write: if request.auth != null;
}
}
}
Your question wasn't entirely clear on what "set firebase security rules as public" specifically means. Your rules already allow full public read access to your default storage bucket. If you want to also allow full public write access, simply remove the condition from the "allow write" line.
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read;
allow write;
}
}
}
This is generally a bad idea, as it allows anyone with an internet connection to fully modify and delete anything and everything in your storage bucket. If you want to learn how to correctly use security rules, you should start with the documentation.

Why am I getting this error? I have pasted my rules below. I have implemented these rules for both storage and cloud firestore.
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read: if request.auth != null;
allow write: if false;
}
}
}
These are automated alerts by firebase. IMHO sometimes they are false positives. In this case, they deemed it insecure because
any logged-in user can read your entire database
If this is the intended behavior you can safely ignore this alert. Otherwise, create more precise rules for each collection/document.
I'm trying to set custom claims using the following:
admin.auth().setCustomUserClaims(user.uid, {['hguwukrpyrwxerqr679p']: true});
where hguwukrpyrwxerqr679p is a unique ID of an object in the firestore database. This object, when it was created, has its own bucket. This bucket has the following security rule:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
allow read: if request.auth.token[bucket];
allow write: if false;
}
}
Unfortunately, this does not work and I get a 403 error code. I don't know why and I've tried simulating the request in the rule-playground of firebase storage, using the user from above. The token section does not show any custom claims at all, but it should, shouldn't it?
I've been at it for quite a few hours now, trying out various methods, even setting the claims manually in a cloud function. Can someone point me in the right direction or give hints on how to debug this problem correctly? When debugging a cloud function by executing
console.log(Object.keys(await admin.auth().getUser(uid).customClaims));
it shows the correct contents.
Rules stored in the root of a bucket are somehow ignored.
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
allow read: if request.auth.token[bucket];
allow write: if false;
}
}
Instead, a wildcard should be used
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{somePath=**} {
allow read: if request.auth.token[bucket];
allow write: if false;
}
}
}
I'm not sure if this should be accepted as an answer since it's only partially relevant to the problem.
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;
}
}
}
I'm using Firebase Firestore to collect user information in my current Android app. But I didn't quite get the Firestore rules. I write the rule like this:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}
But I want to user access the database even there's no current user because when the user sign up I'm checking the database if there's a current phone number in the database if not user can sign up this phone number. Thank you
// Allow read/write access to all users under any conditions
// Warning: **NEVER** use this rule set in production; it allows
// anyone to overwrite your entire database.
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
Not recommended: Read and write access to all users.
Have a look at Fix insecure rules documentation from firebase for more details.
I have a firebase storage download url, like
https://firebasestorage.googleapis.com/v0/b/siren-5eee7.appspot.com/o/profile%2FC6jNlR0F4cZBPv7wF0REWUNVor33?alt=media&token=63a9130e-2ba6-4f38-ac3f-2231c54a1043
How can I access this url without token parameter?
For example, If I access above url without token there will be 403 error showing permisson denied.
My firebase storage secure rule is below :
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
This file located in /etc file. How can I do it?
Try changing rule:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read;
allow write: if request.auth != null;
}
}
}
In case you need the rule to allow accessing only the images without a token you have to do the following:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read: if request.auth!=null || resource.contentType.matches('image/.*');
allow write: if request.auth!=null;
}
}
}
From what I understand, you're trying to make the whole bucket publicly available. Using Firebase access rules might not be best, you might want to make the bucket read access available via Google Cloud's Storage layer.
To do that, one of the easiest way is using the Google Cloud Console Storage.
Select the bucket, click the bucket to configure and open the permissions tab.
Since this is Firebase managed bucket, it would have what Google called fine-grained access control. Don't worry, adding public access is quite simple.
Click Add members button, then, on the sidebar, add in allUser as new member, and give it the role of Storage > Storage Object Viewer. You can see more detail in the Storage Docs.
This will make the bucket publicly viewable via <bucketname>.storage.googleapis.com.
If you created extra bucket in Firebase that match a domain you own and verified in Google Search Console, you can create a bucket of named after your custom domain and have it publicly accessible using a CNAME of the custom domain that points to c.storage.googleapis.com. You can see more detail at Storage Endpoints Docs, Google Cloud's docs explain it much better than I can. Hope this helps!
If you need to access to certain url (image) without token parameter use the rule below:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /images/users/default.png {
allow read;
}
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
If you need to access to certain folder without token parameter use the rule below:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /images/{wildcardpath=**} {
allow read;
}
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
Note: Change the url or folder to yours
