How to Fix CVE-2026-76179

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-2026-76179, 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-598: Use of HTTP Request With Sensitive Query String, where the web application uses an http method to process a request, but the request includes sensitive information in the query string. 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

An improper protection of authentication tokens vulnerability exists in certain Ebyte gateway products. Authentication tokens used by the web management interface are insufficiently protected during client-side session handling, which may allow an attacker with access to exposed session information to obtain and reuse a valid token. Successful exploitation could allow an attacker to impersonate an authenticated user and gain unauthorized access to device management functionality.
