Overview

Review needed

1 high or critical finding category to review

GOLFNETWORKPLUS - GolfScore (com.asai24.golf) scored grade F, 22 out of 100, in a static scan of version 20.9.0 on 2026-10-12. It has 1 high or critical finding among 8 finding categories across 42 occurrences. One finding was confirmed live: an anonymous request reached a backend the app references and it answered without authentication. No credential was used and no stored data was read. 9 tracking SDKs are present in the package, which describes what ships, not what runs or what it sends. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.

Start with these findings

criticalAmazon S3 bucket reference — confirmed publicly readable31 occurrences

Interpretation & review guidance

A reference to an Amazon S3 bucket. Using cloud storage is normal — the risk exists only if the bucket allows anonymous listing/read, which requires a separate authorized assessment.

Evidence
31 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
Verification
1 historically verified occurrence at the recorded scan time. Current reachability is not established.
mediumCleartext (HTTP) traffic permitted1 occurrence

Interpretation & review guidance

The manifest permits cleartext (HTTP) traffic. Data sent over plain HTTP can be read or tampered with on the network; modern apps should require HTTPS.

Evidence
1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
Verification
Static detection; current reachability is not established.
mediumcom.squareup.okhttp3:okhttp 3.12.1 — CVE-2021-03411 occurrence

Interpretation & review guidance

The app bundles a third-party library whose declared version matches a public security advisory (CVE). This is flagged from the version the library itself ships and a curated advisory list — confirm exploitability in your context and update the dependency to the fixed version. It is not a proof of live exploitation.

mediumShort signing key (RSA 1024-bit)1 occurrence

Interpretation & review guidance

The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).

lowData Safety label omits Calendar2 occurrences

Interpretation & review guidance

The app's Google Play Data Safety label omits a data category it can actually access — a permission it requests, or an advertising/device identifier it references. Under-declaring collection is a Play policy issue and a COPPA/privacy concern. This is a static signal: a requested permission is capability, not proof of collection — confirm against runtime behavior.

A Firebase Realtime Database URL. Nearly every app that uses Firebase ships one. It's only an exposure if the database rules are world-readable — that's what live verification checks.

lowFirebase Storage bucket reference2 occurrences

Interpretation & review guidance

A Firebase Cloud Storage bucket reference (the default <project>.appspot.com). Storing user files here is normal — it's only an exposure if the Storage security rules allow public read/list, which live verification tests.

lowGoogle API key (client-shipped; restriction unverified)3 occurrences

Interpretation & review guidance

Android apps are designed to ship Google API keys in the client; Google restricts them by app signing certificate + enabled API. This is only a problem if the key is left unrestricted — presence alone is expected, not an exposure.

Evidence
3 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.

  • Precise location, Approximate location requested while 3 ad/attribution SDK(s) are present (Google AdMob, Meta Audience Network, Moat) — location commonly feeds ad targeting.
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +3 more) with 6 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Calendar, Contacts, Personal info, Phone, Photos & files data requested with third-party analytics/ad SDKs present.

This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.

⚠ Possible Data Safety mismatch. Label omits 2 categories the app can access: Calendar, Contacts.

We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.
