Finding evidence

Open a category to review its occurrences. Printing includes all categories and occurrences.

Application data is backup-enabled · info · 1 occurrence

Backup is on by default on Android; this manifest states it explicitly. If the app stores sensitive local data, define dataExtractionRules/fullBackupContent to exclude it, or set android:allowBackup=false.

CWE-530 · CWE-312 · MASVS-STORAGE-1 · MASVS-STORAGE-2

  • android:allowBackup="true"
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 · 1 occurrence

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

  • AIza•••••••• (21–40 chars, redacted)
Exported content provider without permission (third-party library artifact, shared across 94 unrelated developers) · low · 1 occurrence

Set android:exported=false, or require a signature-level android:permission, and scope grantUriPermissions narrowly.

CWE-926 · CWE-284 · MASVS-PLATFORM-1

  • ClipboardFileProvider (exported, no permission)
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

  • ████████████
Sentry DSN · low · 2 occurrences

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.de.sentry.io/███
