Advisory Summary

CVE-2026-8374 is a HIGH security vulnerability vulnerability (CWE-1204: Generation of Weak Initialization Vector (IV)) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses a cryptographic primitive that uses an initialization vector (iv), but the product does not generate ivs that are sufficiently unpredictable or unique according to the expected cryptographic requirements for that primitive.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-8374

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-2026-8374, 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-1204: Generation of Weak Initialization Vector (IV), where the product uses a cryptographic primitive that uses an initialization vector (iv), but the product does not generate ivs that are sufficiently unpredictable or unique according to the expected cryptographic requirements for that primitive. 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

Misuse and misconfiguration in Bluetooth communication in SwitchBot Door Lock Series allows an attacker to bypass the electronic lock and access controls via a manipulated communication protocol.
