CVE-2026-4607Network attack vector

Subscriber-level group settings modification via unchecked AJAX actions

Published May 13, 2026 · Updated May 13, 2026

Missing authorization in ProfileGrid 5.9.8.4 and earlier allows remote authenticated users to modify site-wide group settings via AJAX. The pm_set_group_order, pm_set_group_items, and pm_set_field_order handlers accept requests without capability checks and write group menu order, list order, icon-display, and field-order settings. Subscriber-level WordPress access is sufficient; exploitation changes shared ProfileGrid configuration but does not provide reported data disclosure or service interruption.
