CVE-2024-33564Network attack vector

Subscriber-level option updates via unchecked settings name

Published Jun 9, 2024 · Updated Apr 28, 2026

Missing authorization in 8theme XStore 9.3.8 and earlier allows remote authenticated users to update arbitrary WordPress options via AJAX. The wp_ajax-connected xstore_panel_settings_save function passes the POSTed settings_name to update_option without a capability check, nonce check, or option-name allowlist. Subscriber-level access reaches the handler and permits settings changes, but the disclosed input structure does not fully control option values and did not yield Administrator escalation.
