Finding evidence
Open a category to review its occurrences. Printing includes all categories and occurrences.
Firebase Realtime Database reference — confirmed publicly readable · critical · 2 occurrences
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

Slack incoming webhook URL · high · 1 occurrence
Remove the hard-coded credential from the app package, rotate/revoke it immediately, and move the secret to a backend the app calls with per-user authentication.
CWE-798 · MASVS-STORAGE-1
https://█████.slack.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.
