Editor-to-Administrator escalation via unrestricted option import
Published Aug 27, 2026 · Updated Aug 27, 2026
Improper privilege management in NiteoThemes CMP before 4.1.18 allows remote authenticated users to escalate from Editor to Administrator. The cmp_ajax_import_settings AJAX action imports attacker-selected option names without enforcing an allow-list, permitting arbitrary WordPress option writes. Reachability requires an administrator to grant Editors access to CMP admin-bar controls; successful exploitation grants full site administration.
