UnverifiedFirebase security rules are the access control mechanism of Firebase cloud databases, and their default basis for judgment is the requester's identity rather than payment status; they can only verify whether a user is himself, not whether the user actually paid, and the correct approach is to leave the writing of subscription status entirely to a trusted backend, with the client having only read-only permissions.76% similarUnverifiedThe concept in Firebase that corresponds to RLS is Firestore Security Rules, which completes permission interception by using rule expressions to determine whether request.auth.uid matches the user ID field stored in the document75% similarVerifiedStoring API keys as environment variables rather than hardcoding them in the source code is a security best practice.72% similarVerifiedIn BYOK mode, API keys are stored in plaintext in local configuration files, posing a security risk of key leakage71% similarVerifiedIt is recommended to store API keys in environment variables or dedicated secrets management services (such as AWS Secrets Manager, HashiCorp Vault, or GCP Secret Manager) rather than hard-coding them in source code69% similar
