Advisory Summary

CVE-2026-105156 is a LOW (CVSS 3.7) security vulnerability vulnerability (CWE-326: Inadequate Encryption Strength) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-105156

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-2026-105156, 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-326: Inadequate Encryption Strength, where the product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. 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

A weakness has been identified in YzmCMS up to 7.6. Impacted is the function Password of the file /common/function/system.func.php of the component MD5 Handler. Executing a manipulation of the argument pass can lead to password hash with insufficient computational effort. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The vendor kindly explains: "Our regular release cycle is about 6 months. The last release was in the previous month, and our next scheduled version will be released in March 2027. We will implement the backward-compatible gradual hash migration feature in this upcoming release. (...) Before the new version is available, we will publish security mitigation guidance on our official documentation for existing deployers to reduce the risk."
