Divi Ajax Filter - Security Vulnerability (CVE-2026-11613)

CVE-2026-11613

Vulnerability CVE-2026-11613 PLUGIN divi-ajax-filter CRITICAL

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'.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

AI risk score 100/100 (Critical, Very High) with priority P1 Immediate. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Patch immediately Serious, and reachable without meaningful privilege.

Fix it

Update Divi Ajax Filter to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
