MEDIUM CVE-2026-16590 Deferred

WP Directory Kit authenticated action dispatch exposes contact messages

WP Directory Kit before 1.5.5 registers wp_ajax_wdk_admin_action for authenticated users. Wpdirectorykit_Admin::ajax_admin() accepts the POST page and function values and passes them to Winter_MVC_WDK->load_controller() without a capability check or nonce. A Subscriber can select an affected controller operation and retrieve private contact messages and associated user data. Version 1.5.5 restricts the allowed page value.

Weakness
CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor

This CVE was published Aug 08, 2026 and is one of 31 known issues for this plugin.

Update, patch or deactivate.

Update to 1.5.5 or later. Review access logs for wdk_admin_action requests from low-privilege accounts and assess whether exposed message contents or personal data require notification or credential rotation.

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
