Overview

Analysis recorded

6 finding categories to review

Web Video Cast | Browser to TV (com.instantbits.cast.webvideo) scored grade B, 85 out of 100, in a static scan of version 6.0.3 on 2026-10-12. It has no high or critical findings, and 6 lower-severity finding categories across 13 occurrences. 15 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.

mediumcom.squareup.okhttp3:okhttp 3.12.13 — 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.

Verification
Static detection; current reachability is not established.
Open in all findingsRequest a correction
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).

Interpretation & review guidance

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.

lowGoogle API key (client-shipped; restriction unverified)2 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.

infoApplication data is backup-enabled1 occurrence

Interpretation & review guidance

The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.

  • Approximate location, Precise location requested while 8 ad/attribution SDK(s) are present (AppLovin, Google AdMob, InMobi +5 more) — location commonly feeds ad targeting.
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +1 more) with 12 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera, 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.

✓ No obvious mismatch between the declaration and what we observe.

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.
