Advisory Summary

CVE-2026-102370 is a MODERATE security vulnerability vulnerability (CWE-1191: On-Chip Debug and Test Interface With Improper Access Control) affecting Software libraries in the Maven ecosystem. The weakness occurs when the chip does not implement or does not correctly perform access control to check whether users are authorized to access internal registers and test modes through the physical debug/test interface.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-102370

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-102370, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1191: On-Chip Debug and Test Interface With Improper Access Control, where the chip does not implement or does not correctly perform access control to check whether users are authorized to access internal registers and test modes through the physical debug/test interface. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Kasa EC70 v4 and EC71 v4 do not logically disable the production debug interface at the firmware or chip level and do not lock the bootloader.  Although the debug traces are physically severed during manufacturing, an attacker with physical access can restore the connection, interrupt the boot process, and manipulate boot parameters to enter a non-standard initialization path that exposes an unauthenticated root shell during startup. Successful exploitation may allow an attacker with physical access to obtain root-level command access during device startup, resulting in loss of confidentiality, integrity, and availability for the affected device. Exploitation requires device disassembly, restoration of the severed debug connection, and manipulation of the boot process.
