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'.

Vulnerability AssessmentAI
| Exploitation | Requires the Divi Ajax Filter plugin (≤5.1.2) installed and active, and - per the description - the 'loop_templates' parameter must be set to 'custom-template', which gates the vulnerable code path; attacks then abuse the 'custom_loop_template' parameter on the AJAX endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) reflects an unauthenticated, network-reachable inclusion flaw, a high-priority pattern for WordPress plugins. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
