CVE-2026-9221
Setracker2 Children's Smartwatch Ecosystem Use of a Broken or Risky Cryptographic Algorithm
Description

The Setracker2 Android Companion App (com.tgelec.setracker) versions 3.1.5 and earlier uses MD5 to generate a request signature for authenticating communications between the mobile client and the backend REST API. Attackers could potentially reverse the signature to recover the session ID. With the session ID exposed, an attacker could impersonate the legitimate user and issue authenticated API requests.
