CVE-2026-9220
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSetracker2 Android Companion App com.tgelec.setracker versions 3.1.5 and prior encrypts requests between the watch and its backend with static hardcoded AES keys and initialization vectors. This allows an attacker to decrypt Setracker2 watch traffic.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Setracker2 Android Companion App (com.tgelec.setracker versions 3.1.5 and prior) uses static hardcoded AES-128/256 encryption keys and initialization vectors to protect communications between the watch device and its backend server. These cryptographic secrets are embedded directly in the application binary, allowing anyone who decompiles the app to extract the keys and decrypt all past and present traffic between devices and the server.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Setracker2 app is installedOn the Android device, go to Settings > Apps > Find 'Setracker2' or search for 'com.tgelec.setracker' in the app list. Alternatively, run 'adb shell pm list packages | grep setracker' to list the package.Affected if The package com.tgelec.setracker is present on any device in your environment
-
Identify installed app versionIn Settings > Apps > Setracker2 > App info, note the version number shown. Or run 'adb shell dumpsys package com.tgelec.setracker | grep versionName' to retrieve the version.Affected if The version is 3.1.5 or any version lower than 3.1.5 (e.g., 3.1.4, 3.1.3, 3.0.0)
-
Inspect APK for hardcoded cryptographic keysExtract the APK from the device (using 'adb pull /data/app/*/base.apk') or obtain it from the original source. Decompile using a tool like apktool or jadx. Search within the decompiled resources and smali/Java files for string patterns resembling AES keys (look for 16 or 32 byte hexadecimal or base64 strings that may represent encryption keys, and any 'IV' or 'initVector' string literals).Affected if Hardcoded AES-128 (16-byte) or AES-256 (32-byte) key values and corresponding IV strings are found embedded in the application code or resources
Your environment is affected if the Setracker2 app (com.tgelec.setracker) version 3.1.5 or prior is installed on any device, and the APK contains static hardcoded AES encryption keys.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace hardcoded AES keys with dynamically generated keys using a proper key exchange or derivation mechanism (e.g., TLS with certificate pinning, ECDH key exchange, or Android Keystore-backed keys). The backend must also be updated to support dynamic key management.
