Advisory Summary

CVE-2026-18013 is a MODERATE (CVSS 4.3) security vulnerability vulnerability (CWE-451: User Interface (UI) Misrepresentation of Critical Information) affecting Software libraries in the Maven ecosystem. The weakness occurs when the user interface (ui) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. this is often a component in phishing attacks.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-18013

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-2026-18013, 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-451: User Interface (UI) Misrepresentation of Critical Information, where the user interface (ui) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. this is often a component in phishing attacks. 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

Inappropriate implementation in Chrome for iOS in Google Chrome on iOS prior to 151.0.7922.72 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)
