Finding evidence
Open a category to review its occurrences. Printing includes all categories and occurrences.
Firebase Realtime Database reference · low · 1 occurrence
Confirm the bucket/database denies anonymous read (enable auth / storage rules / RLS), then audit its contents for data already exposed while it was open.
CWE-200 · CWE-284 · MASVS-STORAGE-2
https://███████████████████████.firebaseio.com/███
Google API key (client-shipped; restriction unverified) · low · 3 occurrences
Restrict the API key (application + API restrictions in Google Cloud Console); a client-shipped key is public, so restriction is the control.
CWE-798 · MASVS-STORAGE-1

Firebase Storage bucket reference · low · 1 occurrence
Confirm the bucket/database denies anonymous read (enable auth / storage rules / RLS), then audit its contents for data already exposed while it was open.
CWE-200 · CWE-284 · MASVS-STORAGE-2
████████████
BIP39 wallet seed phrase (12 words, checksum valid) (third-party library artifact, shared across 12 unrelated developers) · low · 1 occurrence
A mnemonic seed phrase must never be embedded — any holder controls the wallet. Move funds to a new wallet immediately and never bundle key material.
CWE-312 · CWE-798 · MASVS-STORAGE-1 · MASVS-CRYPTO-2
BIP39 mnemonic (12 words) — redacted
Sentry DSN · low · 1 occurrence
A client DSN is low-risk but confirm it is a client (not internal) DSN and cannot be abused to spoof events.
CWE-200 · MASVS-STORAGE-2
https://███████.ingest.us.sentry.io/███
Cleartext (HTTP) traffic permitted · medium · 1 occurrence
Set android:usesCleartextTraffic=false and/or a networkSecurityConfig that forbids cleartext; serve all endpoints over HTTPS.
CWE-319 · MASVS-NETWORK-1
android:usesCleartextTraffic="true"

Use an RSA key of at least 2048 bits or an EC P-256 key for signing.
CWE-326 · MASVS-CRYPTO-1
RSA-1024
Ships third-party ad/analytics SDKs but Data Safety declares no data shared · medium · 1 occurrence
Declare third-party data sharing in Data Safety, or confirm and document that the SDKs transmit no user data.
CWE-359 · MASVS-PRIVACY-3
2 ad/attribution SDK(s) present; 'Data shared' is empty
