Local File Inclusion in Divi Ajax Filter WordPress Plugin

Publication date: 2026-09-04

Last updated on: 2026-09-04

Assigner: Wordfence

Description
The Divi Ajax Filter plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 5.1.2 via the 'custom_loop_template' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. This vulnerability is only exploitable when the loop_templates parameter is set to 'custom-template'.

Executive Summary

The Divi Ajax Filter plugin for WordPress has a Local File Inclusion vulnerability in versions up to 5.1.2. The 'custom_loop_template' parameter allows unauthenticated attackers to include and execute arbitrary PHP files on the server. This can lead to code execution, bypassing access controls, or stealing sensitive data. The flaw is only exploitable when the loop_templates parameter is set to 'custom-template'.

Detection Guidance

Check if the Divi Ajax Filter plugin version is 5.1.2 or lower. Look for unusual PHP file inclusions in web server logs, particularly requests to the 'custom_loop_template' parameter. Inspect WordPress installations for unauthorized .php file uploads or executions.

Impact Analysis

An attacker could exploit this to run malicious PHP code on your server, steal sensitive data, bypass security controls, or take full control of your WordPress site. This could lead to website defacement, data breaches, or further attacks on your server or users.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection. A breach may result in legal penalties, fines, and reputational damage due to non-compliance with data security standards.

Mitigation Strategies

Update the Divi Ajax Filter plugin to version 5.1.3 or higher immediately. Disable the plugin if an update is not possible. Review server logs for signs of exploitation and remove any unauthorized files. Ensure file upload restrictions are in place to prevent .php file uploads.
