Advisory Summary

CVE-2026-5137 is a MODERATE (CVSS 4.3) security vulnerability vulnerability (CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the php application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in "require," "include," or similar functions.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-5137

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-2026-5137, 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-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion'), where the php application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in "require," "include," or similar functions. 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

The RTMKit (rometheme-for-elementor) plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 2.0.7 This is due to insufficient path validation on the 'template' parameter in the render_templates AJAX endpoint, which is used directly in a require/include statement without sanitization. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute files on the server ending in _templates.php, allowing the execution of any PHP code in those files.
