CVE-2026-4216 — A weakness has been identified in i-SENS SmartLog App up to 2.6.8 on Android

Medium CVSS 5.3

A weakness has been identified in i-SENS SmartLog App up to 2.6.8 on Android. This affects an unknown function of the component air.SmartLog.android. This manipulation causes hard-coded credentials. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. The vendor explains: "The function referenced in the report currently exists in our deployed system. It is related to a developer mode used during the configuration process for Bluetooth pairing between the blood glucose meter and the SmartLog application. This function is intended for configuration purposes related to device integration and testing. (...) [I]n a future application update, we plan to review measures to either remove the developer mode function or restrict access to it."

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
