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 · 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 · medium · 1 occurrence
Set android:exported=false, or require a signature-level android:permission, and scope grantUriPermissions narrowly.
CWE-926 · CWE-284 · MASVS-PLATFORM-1
ExportFileProvider (exported, no permission)
Short signing key (RSA 1024-bit) · medium · 1 occurrence
Use an RSA key of at least 2048 bits or an EC P-256 key for signing.
CWE-326 · MASVS-CRYPTO-1
RSA-1024
