Open storage buckets in Firebase

criticalUpdated Oct 12, 2026

Fix for Firebase

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /uploads/{userId}/{file} {
      allow read, write: if request.auth != null && request.auth.uid == userId;
    }
  }
}

That sample is the shape, not a complete ruleset. Add size and content-type checks from unsafe file uploads. Do not deploy if true because a test upload failed.

The five-minute check, the other platforms, and the agent prompt are on the full guide. More Firebase fixes are on the Firebase page.
