CVE-2026-9219
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 have a predictable registration ID derived from IMEI. The enrollment system lacks additional authentication before assignment. If an attacker is able to obtain the registration ID, they would be able to arbitrarily enroll watches belonging to other users.
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 versions 3.1.5 and prior uses a predictable registration ID mechanism derived from the device IMEI. The enrollment system fails to require additional authentication before assigning a watch to a user account, allowing an attacker who obtains a valid registration ID to hijack and arbitrarily enroll watches belonging to other users.

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.
-
Locate Setracker2 app installationOpen Android Settings > Apps > Find 'Setracker2' or 'Setracker' in the installed applications list. Alternatively, use ADB command: pm list packages | grep setrackerAffected if The Setracker2 Android Companion App is installed on the device
-
Determine installed app versionIn Android Settings > Apps > Setracker2 > App info, view the Version name and Version code. Compare numerically to 3.1.5 (version 3.1.5 or any lower version number is affected)Affected if The installed version is 3.1.5 or any prior version (e.g., 3.1.4, 3.1.0, 3.0.x)
-
Verify watch pairing functionality is accessibleOpen the Setracker2 app and navigate to the Add Device / Pair Watch / Enroll section. Attempt to access the enrollment flow to confirm the feature is present and activeAffected if Watch pairing or device enrollment feature is available and accessible in the app
You are affected if the Setracker2 Android Companion App is installed at version 3.1.5 or prior and the watch pairing/enrollment feature is accessible, as the predictable IMEI-derived registration ID mechanism allows unauthorized watch hijacking.

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 the IMEI-derived registration ID with a cryptographically random identifier and implement multi-factor or additional authentication (e.g., device ownership verification, OTP, or binding confirmation) before allowing watch assignment to prevent unauthorized enrollment.
