Email disclosure and CRM re-sync via unchecked AJAX
Published Oct 1, 2026 · Updated Oct 1, 2026
Access control flaws in Jack Arturo WP Fusion Lite before 3.48.0 allow remote authenticated users to list other users' emails and re-sync CRM contacts. The activity-log search and user re-sync admin AJAX handlers accepted a nonce available from a subscriber's own profile without checking the capabilities needed for those actions. A subscriber account and that profile nonce are required; the documented effects are email disclosure and cross-user CRM re-sync, not CRM data deletion.
