CVE-2026-11359Network attack vector

Subscriber-level unauthorized plugin installation via unchecked AJAX handler

Published Jul 9, 2026 · Updated Jul 9, 2026

Missing authorization in ProfileGrid WooCommerce Integration 3.4 and earlier allows remote authenticated users to install and activate ProfileGrid. The pg_install_profilegrid() AJAX handler accepts an authenticated wp_ajax_pg_install_profilegrid request without a capability check or nonce validation, then installs and activates the plugin. Subscriber-level access is sufficient, and the bounded consequence is an unauthorized change to the site's installed and active plugins.
