Official 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'.
