HIGH CVE-2026-18230 Deferred

WP Directory Kit admin action permits Subscriber SQL injection

WP Directory Kit before 1.5.6 registers the authenticated wp_ajax_wdk_admin_action action. Its dispatcher accepts page=wdk_fields without a capability check, allowing a Subscriber to reach Wdk_fields::field_edit(). That method uses the posted section value while updating field section and order data, producing SQL injection. Version 1.5.6 adds an Administrator-only controller guard.

CWE-89 — Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

This CVE was published Aug 12, 2026 and is one of 31 known issues for this plugin.

Update, patch or deactivate.

Update to 1.5.6 or later. Review Subscriber-level wdk_admin_action requests and database logs for injection probes, and rotate secrets if database information may have been extracted.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The WP Directory Kit WordPress plugin before 1.5.6 does not sanitise and escape a parameter before using it in a SQL statement through one of its authenticated AJAX actions, which lacks an authorization check, allowing any authenticated user such as a Subscriber to perform SQL injection attacks.
