CVE-2026-120554

The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.5.11 This is due to a non-atomic multi-option write sequence in the ACUI_Cron::save_settings() function, which persists acui_cron_activated, acui_cron_configured_by, acui_cron_user_id, and acui_cron_path_to_file before reaching the authorization gate that calls wp_die() when a non-promoter submits a role. This makes it possible for authenticated attackers holding a custom delegated role with create_users but without promote_users or edit_users to escalate their privileges to Administrator, provided a prior administrator cron-tab save exists and no successful save intervenes before the next unattended cron tick processes the attacker's repointed CSV file.
