Authenticated options changes via unchecked AJAX authorization
Published Jun 7, 2023 · Updated Apr 8, 2026
Missing authorization in Mesmerize 1.6.89 and earlier and Materialis 1.0.172 and earlier allows remote authenticated users to alter options. The companion_disable_popup AJAX handler verifies a nonce but performs no capability check before passing attacker-controlled option names and integer values to update_option. Subscriber-level access exposes the nonce and permits restricted wp_options changes, including open registration, plugin deactivation, or a site crash.
